Reaction Steps

To a solution of 105 mg (1.6 mmol) of KCN in 1 mL of water, 220 mg (0.8 mmol) of 2-bromo-4′-phenylacetophenone in 3 mL of MeCN was added. The mixture was warmed in a 50° C. bath to dissolve some of the halide. After ˜20 min the solids dissolved. The reaction was stirred for 30 min, then partitioned between 1.2 N HCl and EtOAc. The organic layer was washed with brine, dried and concentrated leaving 210 mg of the title compound which was used in the next step without purification.
