N-Methylisopropylamine → 10-bromo-9-fluoro-3-((isopropyl(methyl)amino)methyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide

Participants

Reaction Steps

10-bromo-9-fluoro-3-formyl-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide (75 mg) was reacted with N-Isopropylmethylamine similarly to as described in the synthesis of 9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-3-[(4-methylpiperazin-1-yl)methyl]-5,6,7,12-tetrahydro-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide afford 10-bromo-9-fluoro-3-((isopropyl(methyl)amino)methyl)-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 E to afford 31 mg (35%) of 9-fluoro-10-(3-hydroxy-3-methyl-but-1-ynyl)-3-[[isopropyl(methyl)amino]methyl]-5,6,7,12-tetrahydro-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxamide.
