Reaction Steps

A 0° C. solution of Example 1E (80 mg, 0.31 mmol) in dichloromethane (4 mL) was treated with pyridine (0.03 mL, 0.38 mmol) and benzoyl chloride (0.038 mL, 0.32 mmol), stirred at 0° C. for 1 hour, then at room temperature overnight. The reaction mixture was diluted with water and extracted twice with dichloromethane. The combined extracts were washed with brine, dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with ethyl acetate to provide 39 mg (35%) of the desired product. 1H NMR (300 MHz, DMSO-d6) δ 10.46 (s, 1H); 8.28 (s, 1H); 7.98 (d, J=8.1 Hz, 4H); 7.63-7.54 (m, 3H); 7.40 (d, J=8.1 Hz, 2H); 2.31 (s, 3H); HRMS(ESI) Calcd. for C20H17N4OS: 361.1118. Found: 36.1122.
