実験手順

Here, [4-(2-chlorophenyl)-9-methyl-6H-thieno[3,2-f][1,2,4]-triazolo[4,3-a][1,4]diazepin-2-yl]-methane carboxylic acid (20 g, 0.054 mol), tetrahydrofuran (500 ml) and 1,1'-carbonyldiimidazole (10 g) are stirred for 1 hour at ambient temperature and the solution, now clear, is mixed with morpholine (0.06 mol, 5.2 g). After stirring overnight at ambient temperature, evaporation, taking up in methylene chloride, washing with sodium bicarbonate solution and filtering through a column of SiO2, the title compound (9.4 g), m.p. 143°-144° C., is obtained by recrystallization from ethyl acetate.
