2-Ethoxybenzaldehyde Use and Manufacturing

Methods of Manufacturing

General procedure: A mixture of 1b (100 mg, 0.818 mmol), SS-Pd (918 mg, 0.04 mmol Pd) and 3 ml of toluene was purged with molecular oxygen and stirred at 110 °C for 5 h. The progress of reaction was monitored on TLC. After completion of reaction, the reaction was cooled, diluted with ethyl acetate and filtered through cotton bed. The combined organic layer was evaporated under reduced pressure and crude residue was purified by silica gel (mesh 60-120) column chromatography (Hexane/EtOH 95:5) afforded 2b as colorless liquid (94 mg, 96percent).General procedure: Salicylaldehyde (5) (3.66 g, 3.2 mL, 30 mmol) was added to asuspension of potassium carbonate (8.29 g, 60 mmol) in DMF(50 mL). Alkyl halide was then added dropwise and the solutionwas stirred for 36 h under an atmosphere of argon.Water (150 mL)was added and the mixture was extracted with diethyl ether(3 50 mL). The combined organic layers were washed with 2MNaOH (3 50 mL), dried over Na2SO4, filtered and evaporated invacuo to afford the 2-alkoxy benzaldehyde 6a-b.

Uses

Used as a pharmaceutical intermediate for the synthesis of high-efficiency anti-inflammatory drugs diclofenac
