PROCEDURE

实验过程

Compound (34) obtained in step (2) above (1.50 g) was dissolved in a mixture of trifluoroacetic acid-dichloromethane (1:4) (25 ml), and the solution so obtained was allowed to stand at room temperature overnight so that there occurred de-esterification of compound (34). The resulting reaction solution was concentrated to leave a solid. This solid was then washed with diethyl ether to yield the titled compound (35) (1.31 g) which was insoluble in diethyl ether (1.31 g). Yield: 97%.
