2-(Trifluoromethyl)benzoyl chloride → N-[4-((6,11-Dihydro-5H-dibenz[b,e]azepin-5-yl)carbonyl]phenyl]-2-trifluoromethylbenzamide

Participants

Reaction Steps

As described for Example 9, a mixture of 0.377 g (1.44 mmol) of 5-(4-aminobenzoyl)-6,11-dihydro-5H-dibenz[b,e]azepine, 0.15 g of triethylamine and 0.300 g (1.44 mmol) of 2-trifluoromethylbenzoyl chloride is stirred at room temperature for 2 hours and then washed with 1N HCl 1M NaHCO3, brine and dried (Na2SO4). The solution is passed through a thin pad of hydrous magnesium silicate and the filtrate evaporated to give a solid. Crystallization from dichloromethane-hexane gives 0.41 g of crystals, m.p. 191°-193° C.
