Procedure

Borane methyl sulphide (2.0 M in toluene, 1.3 mL, 2.6 mmol) was added to compound 3 (0.4 g, 2.2 mmol) in toluene (10 mL) under nitrogen. After heating to 60° C. for 3 hours, the mixture was allowed to cool, and 15 mL methanol was added followed by 15 mL 4 M HCl in dioxane. After reflux for 1 hour, the mixture was evaporated to dryness. Crystallization from ethyl acetate gave the required product as colorless crystals (0.23 g, 47%); mp 170–173° C.
