Procedure

3-(Aminomethyl)-10-bromo-9-fluoro-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide was reacted with cyclobutanecarboxylic acid similar to as described in example 2 with non-critical modifications to afford crude 10-bromo-3-(cyclobutanecarboxamidomethyl)-9-fluoro-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide which was directly reacted with 2-methyl-3-butyne-ol via General Procedure F to afford 12 mg (29.3%) of 3-[(cyclobutanecarbonylamino)methyl]-9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-5,6,7,12-tetra hydro-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide.
