Participants

Reaction Steps

Methyl 10-bromo-3-formyl-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate was reacted with pyrrolidine similarly to as described in Example 7 to afford 320 mg (70%) of methyl 10-bromo-3-(pyrrolidin-1-ylmethyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate as a white solid. methyl 10-bromo-3-(pyrrolidin-1-ylmethyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate was subjected to General Procedure L to afford 130 mg (47%) of 10-bromo-3-(pyrrolidin-1-ylmethyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide. 10-bromo-3-(pyrrolidin-1-ylmethyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide was reacted with (3R)-3-ethynyl-3-hydroxy-1-methyl-pyrrolidin-2-one similarly to as described in General Procedure F with non-critical modifications to afford 14 mg (19%) of 10-[2-[(3R)-3-hydroxy-1-methyl-2-oxo-pyrrolidin-3-yl]ethynyl]-3-(pyrrolidin-1-ylmethyl)-5,6,7,12-tetrahydro-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide.
