Reaction Conditions

Reaction Steps

To a solution of Example 91B (1.56 g, 8 mmol) in MeOH (15 mL) was carefully added KCN (0.8 g, 12.3 mmol) and the mixture was warmed at 35° C. for 48 hours. The mixture was diluted with 50 mL ethyl acetate, washed with conccentrated aqueous NaHCO3 (20 mL) and brine (10 mL). The aqueous solution was oxidized with excessive NaC100. The organic phase was dried over MgSO4, filtered, and concentrated to give the title compound as an oil which was used directly for the next step (1.35 g, 90%). LC-MS: m/z (M+H): 161.
