Procedure

To a solution of 4-bromo-N-cyclopropyl-2-methyl-benzamide (Intermediate 157, 1.81 g, 7.12 mmols) in THF (12 mL) was added BH3.SMe2 (1.08 g, 14.24 mmols). The solution was heated to 60° C. for 6 hours, cooled to room temperature and carefully treated with saturated aqueous Na2CO3 (30 mL) and stirred for 17 hours. This mixture was extracted with EtOAc and the combined organic layers were washed with H2O saturated aqueous NaCl before being dried (MgSO4) and concentrated under reduced pressure. The title compound was isolated by column chromatography (10-15% EtOAc-hexanes).
