Reaction Steps

In a sealed tube, 60 mg (134 μmol) of methyl 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-(cyclopropylmethyl)-2-oxopiperidin-3-yl)acetate (Example 47) and 4.8 mL of a solution of ammonia in methanol (7N, 3.4 mmol) were stirred at 25° C. for 5 days. Then NaCN (3 mg) was added and the resulting solution was stirred at 50° C. for 3 days. Excess NH3 and MeOH were removed under reduced pressure. Separation by reversed phase HPLC (10 to 90% AcCN/H2O in 45 min) provided the title compound as a a white solid.
