Procedure

A solution of Intermediate 111.1 (40 mg, 0.05 mmol) and NaBH4 (5 mg) in 1 mL MeOH was stirred for 0.5 h at rt. The reaction mixture was partitioned between EtOAc and H2O, the organic layer was collected, dried (Na2SO4), filtered and concentrated to afford 30 mg of Intermediate 111.2. LCMS (2 min gradient) RT=1.49 min, 814.4 (M+H).
