Participants

Reaction Steps

A solution of the product of step (b) (2.6g) in methanol (20ml) was cooled to 0° under nitrogen and treated dropwise with a solution of potassium hydroxide (1.42g) in water (8ml). The mixture was allowed to warm to room temperature over 2 hours and then partitioned between ethyl acetate and water. The aqueous phase was acidified with 2N HCl and the organic phase separated, washed with water and dried. Evaporation yielded an oil which slowly crystallised to give the title product (0.7g) as white crystals. mp 145°-6°.
