참여 물질

반응 단계

A solution of hydrogen chloride (27.1 g) in methanol (192.2 g) is stirred at room temperature and 2-amino-4-chlorobenzoic acid (25 g) is added. The mixture is heated under reflux for 10 hours, then cooled and neutralised with a solution of sodium carbonate (20 g) in water (200 ml). The solid is filtered off, washed with water, and dried in vacuo at 65° C. to give methyl 2-amino-5-chlorobenzoate (15.5 g).
