Procedure
A solution of methyl 4-[5-(4-chlorophenylsulphamoyl)pyrid-2-yl]butanoate (0.8 g), 10% w/v sodium hydroxide solution (5 ml) in ethanol (15 ml) was stirred for 1 hour. The solution was acidified with dilute hydrochloric acid (pH 3) and cooled to 5° C. The white precipitate was collected and recrystallised from ethanol to give the title compound (0.504 g) as prisms. m.p. 150°-152° C.
