実験手順

Under an argon atmosphere at 0° C., a solution of 25.6 mg (0.34 mmol) of 2-methoxy-ethanol in 2 ml of tetrahydrofurane was treated with 15 mg (0.34 mmol) of sodium hydride (55% dispersion in refined oil) and stirred during 15 min. To this mixture, a solution of 100 mg (0.34 mmol) of 3-methylsulfanyl-5-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-[1,2,4]triazine-6-carbonitrile in 3 ml of tetrahydrofurane was added and stirring continued for 18 h at 40° C. The yellow solution was evaporated under reduced pressure and the residue (141 mg) was chromatographed on silica gel with a 99:1 v/v mixture of dichloromethane and methanol as eluent. Thus were obtained 10 mg (9% of theory) of 3-(2-methoxy-ethoxy)-5-(1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-[1,2,4]triazine-6-carbonitrile as a light yellow solid; MS: 326 (M+H)+.
