Procedure

2N Sodium hydroxide solution (40 ml) was added with stirring over 0.25 hour to a solution of the product of part (ii) (23.3 g) in methanol (80 ml) and stirring was continued for a further 0.25 hour. Water (150 ml) was added and the mixture was cooled. The solid was filtered off, washed with water and dried to give the title compounds, (17.4 g), m.p. 148.5°-150.5°.
