Reaction Steps
A suspension of the product of stage (a) (40 g) in aqueous 10% sodium carbonate solution (200 ml) was heated under reflux for 2 hours. The clear yellow solution obtained was cooled and acidified with concentrated hydrochloric acid to afford an off-white precipitate. This was filtered off and recrystallised from ethanol to give the desired product (33 g), as white needles, mp 142°-143° C.
