Procedure

A mixture of compound 102 (0.59 g, 1.90 mmol), triethylamine (1.6 mL, 11.48 mmol), potassium cyanide (0.061 g, 0.93) and 2-hydroxy-2-methylpropanenitrile (1 mL, 10.93) in methanol (15 mL) was stirred at 40° C. for 24 h then solvent evaporated. The resulting crude residue was purified on ISCO (0-100% EtOAc in Hexanes) to afford title compound 103 (0.364 g, 56%) as a yellow solid. LRMS (ESI): (calc) 347.10 (found) 348.4 (MH)+.
