Procedure

To a mixture of 9-(1H-indol-5-yl)-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazine 2,2-dioxide (131 mg) in DMF (dry) (15 ml) was added NaH (60%, 18.38 mg) at room temperature. The mixture was stirred at the same temperature for 10 min. Iodoethane (0.039 mL) was added and the mixture was stirred at room temperature overnight. Water and EtOAc were added and the extracted organic layer was washed with brine. Silica-gel was added to the organic layer and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (NH-silica gel, eluted with MeOH in EtOAc) to give the title compound (34.6 mg) as a white solid.
