Procedure

To a solution of 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxo-1-(pyrimidin-4-yl)piperidin-3-yl)acetaldehyde (Example 110, Step C) (25 mg, 55 μmol) in a mixture of 2-methylpropan-2-ol (1.0 mL) and 2-methyl-2-butene (55 μL, 2.0 M soln in THF, 0.11 mmol) was added a solution of sodium chlorite (37 mg, 0.55 mmol) and sodium dihydrogen phosphate (4.8 mg, 50 μmol) in 550 μL of water at room temperature. The reaction mixture was stirred for 1 hour before it was quenched with water and extracted (2×EtOAc). The combined organic layers were washed with sat. aq. NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. Purification of the residue by silica gel prep plate (10% MeOH/DCM) provided the title compound as a colorless solid.
