Reaction Steps

To a solution of the product of Example 49A (220 mg, 3.64 mmol) in tetrahydrofuran (20 mL) at 0° C. was added borane tetrahydrofuran complex (18 mL, 18 mmol) and the mixture was stirred at 0° C. for 2 hours and at 60° C. for 4 hours. After cooling to ambient temperature, methanol (20 mL) was added and stirring was continued for 30 minutes. The organic phase was concentrated and the residue was purified via preparative HPLC using a gradient of 10/90 to 80/20 acetonitrile/water (containing 0.1% trifluoroacetic acid) to give the title compound. MS: 207 (M+H+).
