실험 절차
2-(2-Chloroethyl)-2,3-dihydro-4-methylpyrido[3,2-f][1,4]oxazepine-5(4H)-thione, 4.5 g (0.018 mole) was dissolved in morpholine (30 ml). The solution was heated with stirring to 50°-60° C. for 6 hr. The morpholine was then removed by rotary evaporation (90° C., vacuum pump). The residue was taken up in chloroform (100 ml) and washed with dilute aqueous sodium hydroxide (2×30 ml). The organic layer was concentrated by rotary evaporation (60° C., water aspirator). The residue was recrystallized from ethanol giving 3.26 g (60%) of light yellow crystals, m.p. 152°-153° C.
