Procedure
Hydrogen chloride gas was passed through a gently boiling solution of 3-(5-acetamido-2-hydroxybenzoyl) propionic acid (1.2g) in dry methanol (20 ml) until esterification was complete. The reaction mixture was then poured into ice-water and chloroform added. The chloroform extract was washed with sodium bicarbonate solution then water, and finally dried and evaporated to leave methyl 3-(5-acetamido-2-hydroxybenzoyl)propionate as a solid (0.75g, 59%; m.p. 145°-147° C; M+, 265, M 265).
