実験手順

57% Sodium hydride in mineral oil (8.4 g., 0.200 mol.) was added to a stirred solution of 28.0 g (0.0834 mol.) of 10-trifluoromethyl-1H-pyrimido[5,4,3-kl]phenothiazine -1,3(2H)-dione in 220 ml. of dry dimethylformamide. The mixture was stirred for 1 hour at 25°, then 54.0 g. (0.432 mol.) of 2-bromoethanol was added. The resulting mixture was stirred for 4.5 hours at 25°, then filtered. The filtrate was evaporated to dryness under reduced pressure and the residue was chromatographed on silica gel with chloroform and 90% chloroform-methanol as eluants to give the title compound, m.p. 90°-93° (methanol).
