Procedure

A solution of the crude product from Step B (2.0 g, 2.3 mmol) in methanol (50 ml) was treated with sodium methoxide (120 mg, 2.2 mmol) for 18 hours at room temperature. The mixture was evaporated, the residue taken up in diethyl ether, acetic acid (1 ml) added, the solution washed three times with water, saturated aqueous sodium chloride solution, dried (sodium sulfate) and evaporated. The crude product was vacuum filtered through a column of silica gel (Merck #7734) eluted with 2:1 hexane-ether; yield 1.5 g.
