Procedure
A suspension of 3,5-difluoroaniline (15.0 g) and sodium bicarbonate (19.5 g) in methyl chloroacetate (15.2 ml) was stirred at 80°-90° under nitrogen for 60 h. More sodium bicarbonate (4.88 g) and methyl chloroacetate (5.1 ml) were added, and the suspension was stirred at 80°-90° for a further 24 h. Work up according to the method of Intermediate 5 gave a solid (16 g) which was recrystallised from chloroform (10 ml) and n-hexane (120 ml) to give the title compound (8.34 g), m.p. 75°-77°.
