Participants

Reaction Steps

10-bromo-2-carbamoyl-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-3-carboxylic acid (0.1 g) was reacted with N,N-Dimethylamine Hydrochloride similarly to the conditions described in Example 2 to produce 10-bromo-N3,N3-dimethyl-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2,3-dicarboxamide. This intermediate was then reacted with (2R)-2-(5-methylisoxazol-3-yl)but-3-yn-2-ol via General Procedure E to afford 21 mg (16%) of 10-[(3R)-3-hydroxy-3-(5-methylisoxazol-3-yl)but-1-ynyl]-N3,N3-dimethyl-5,6,7,12-tetrahydro-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2,3-dicarboxamide.
