Phenyl isocyanate → N-Phenyl-4-(5H,11H-pyrrolo[2,1-c][1,4]benzoxazepine-11-yl)-1-piperidine carboxamide

Participants

Reaction Steps

A solution of 11-(piperidin-4-yl)-5H,11H-pyrrolo[2,1-c][1,4]benzoxazepine (4.8 g, 0.018 mole) and phenylisocyanate (2.14 ml, 0.02 mole) in 140 ml benzene was heated at 65° C. for 1 hour. The reaction mixture was then cooled. The product was filtered and dried to yield 6.25 g (90%) of a solid, m.p. 184°-192° C. This was recrystallized from tetrahydrofuran/diethyl ether (1:4) to yield 5.9 g (85%) of an analytically pure solid, m.p. 167°-170° C.
