Reaction Steps

In a manner similar to that described for Compound 12, the tricyclic bromide (300 mg, 1.13 mmol) and 1-)t-butoxycarbonyl)pyrrole-2-boronic acid (263 mg, 1.24 mmol) were coupled with concomitant removal of the BOC group to yield 2-(1H-pyrrol-2-yl)-1,3,4,5-tetrahydro-azepino[5,4,3-cd]indol-6-one, 81 mg (28% as a greenish grey solid: m.p. >400° C.
