75 °C

To a suspension of compound 45A (400 mg, 2.1 mmol) in MeCN (15 mL) was added trimethylsilylcyanide (0.34 mL, 2.5 mmol), followed by a slow addition of Et3N (0.65 mL, 4.6 mmol). The reaction mixture was heated to 75° C. for 30 min, then cooled to rt, concentrated, dried under vacuum, and purified by silica gel flash chromatography, eluting with CH2Cl2 to give the title compound (150 mg, 36%) as a white solid. LC/MS m/z 200 [M+H]+.
