Drug Information

MeSH：

A class of drugs that act by inhibition of sodium influx through cell membranes. Blockade of sodium channels slows the rate and amplitude of initial rapid depolarization, reduces cell excitability, and reduces conduction velocity. (See all compounds classified as Sodium Channel Blockers.)

Ethyl 4-ethoxybenzoate Use and Manufacturing

Methods of Manufacturing

15 g (0.108 mole) of 4-hydroxybenzoic acid and 54.4 g (0.353 mole) of diethylsulfate were introduced into a glass flask containing xylene (75 ml). The mixture was heated to 90 C. The pH of mass was checked by a calibrated pH electrode immersed in the mass. The pH was maintained between 8-10 by drop wise addition under stirring of a 35percent aqueous NaOH solution [13.6 g (0.326 mole) NaOH flakes in 25 ml water] in 90 minutes. The mass is further stirred for 15 minutes after addition of NaOH. Then the mass was cooled to ambient temperature and 75 ml water was added. The upper organic phase containing the formed product was separated from the lower aqueous phase, washed with General procedure: In a 50 mL two-necked round-bottomed flask equipped with a magnetic stirring bar, a reflux condenser and a calcium chloride drying tube was placed nicotinic acid (1 g, 8.1 mmol) suspended in boron trifluoride etherate (10 mL). The reaction mixture was stirred and heated to 120 °C overnight during which the creamy reaction mixture changed into a brownish solution. Thin layer chromatography (hexane/ethyl acetate 3:1) revealed complete reaction. The cooled reaction mixture was diluted with water (25 mL) and extracted with ethyl acetate (3 x 10 mL). The combined organic extract was washed to the end of effervescence with a saturated solution of NaHCO3. The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo giving a crude yield of 1.11 g (92percent).

Uses

Used in pharmaceutical intermediates and organic synthesis.
