Description
ChEBI: A benzyl ester resulting from the formal condensation of the carboxy group of nicotinic acid with benzyl alcohol. It has been used as a rubefacient.
Benzyl nicotinate is a benzyl ester resulting from the formal condensation of the carboxy group of nicotinic acid with benzyl alcohol. It has been used as a rubefacient. It has a role as a vasodilator agent. It derives from a nicotinic acid.

Benzyl nicotinate Use and Manufacturing
General procedure: Lanthanum nitrate hexahydrate (La (NO 3) 3 .6H 2 0, 17.3 mg, 0.04 mmol) and nitrous oxide were added to a Soxhlet reflux vessel containing absorbent cotton and 2.0 g of dried pelletized molecular sieves 5 A (MS 5 A) , Tri-n-octylphosphine (90percent purity, 40 μL, 0.08 mmol) and dimethyl carbonate dehydrated by distillation (8 mL) were placed and stirred at room temperature for 1 to 2 minutes. The resulting mixture was heated under heating reflux conditions (bath temperature of 110 ° C.) for 1 hour. The mixed solution was cooled to room temperature, the solvent component was distilled off under reduced pressure, and the mixture was dried at room temperature under 5 Torr or less for 1 hour to prepare a catalyst. In the reaction vessel, n-hexane (8 mL) as a solvent, 4-nitrobenzoic acid ester (4.0 mmol) as a carboxylic acid ester and benzyl alcohol (4.0 mmol) as a primary alcohol were added in this order. Immediately, the reactor was heated to reflux condition (bath temperature: 90 ° C.). Refluxing was continued while appropriately checking the progress of the reaction by TLC, and after 5 hours, the completion of the reaction was confirmed by TLC. Thereafter, the reaction mixture was cooled to room temperature, a small amount of water (0.3 to 0.5 mL) was added, and the reaction was stopped by stirring at room temperature for 5 minutes. The reaction mixture was dried over magnesium sulfate, filtered, and the filtrate was concentrated. The product was isolated from the concentrate by silica gel column chromatography (n-hexane: ethyl acetate). The yield was 99percent.In Examples 25 to 29 and Comparative Examples 10 to 14, a product was obtained in the same manner as in Example 24, except that the compound shown in Table 4 was used as the carboxylic acid ester and the reaction time was changed. In addition, in Example 30 and Comparative Example 15, production was carried out in the same manner as in Example 24, except that methyl benzoate was used as the carboxylic acid ester, cyclohexanol as the secondary alcohol was used as the alcohol compound, and the reaction time was changed I got things. However, in Examples 26, 27 and 29 and Comparative Examples 11, 12 and 15, as shown in Table 4, the amounts of lanthanum compounds and ligands used were increased. The results are shown in Table 4 including the results of Example 24 and Comparative Example 9.
benzyl nicotinate can increase skin oxygenation—thanks to vasodilatation properties—and help stimulate the healing process of wounded skin. It is an ester form of niacin (vitamin B), benzyl alcohol, and nicotinic acid.
