Reaction Steps

To a solution of the title product of Example 2 (18.3 g, 114 mmol) in 60 mLof tetrahydrofuran at 0° C. was added dropwise a solution of borane in tetrahydrofuran (175 mL, 1M). After stirring at room temperature for 3 days, 300 mL of water was added followed by solid K2CO3 (31.7 g, 229 mmol). The layers were separated and the aqueous phase extracted with three portions of diethyl ether. The combined organic extracts were washed with brine, dried over magnesium sulfate, filtered and concentrated. The crude product was purified by distillation at reduced pressure (8 mm Hg) to give the title compound (12 g), b.p. 107°-110° C. The structure was verified by NMR.
