Participants

Reaction Steps

To a solution of 1-methylidene-4-phenyl-4-(3-(2-methoxyphenyl)-3-oxo-2-azaprop-1-yl)cyclohexane (Example 165, 117 mg, 0.35 mmol) was added 9-BBN (7 mL, 0.5 N, 3.5 mmol) in THF. The reaction mixture was stirred at rt for 1 h, and then heated to 45° C. for 3 h. To the solution was then added NaOH (3 mL, 10%) and H2O2 (4 mL, 30%) and the mixture was heated at 45° C. for 14 h. The reaction mixture was poured into CH2Cl2 and washed with 2N HCl and dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography (silica, EtOAc/hexane, 2:1) to give the title compound as a 2:1 mixture of two diastereomers.
