Procedure

A solution of propyl 5-amino-2-chlorobenzoate (10.7 g, 0.050 mole) and triethylamine (6 g, 0.059 mole) in methylene chloride (50 ml) was added dropwise over 1 hour to an ice-cooled solution of o-toluoyl chloride (7.8 g, 0.50 mole) in methylene chloride (50 ml). The mixture was then stirred at room temperature for 3 hours and worked up by washing sequentially with water, dilute hydrochloric acid, water, 2% aqueous sodium hydroxide and water. The residue from evaporation of the methylene chloride was recrystallized from ethanol (100 ml) to give the title compound, m.p. 103°-105° C. (7.5 g, 45% yield).
