Acetyl chloride → HCID 21546072, compound

Participants

Reaction Steps

A solution of 3.9 g. of acetyl chloride in 25 ml. of chloroform is added to a cooled solution of 11.0 g. of 1-cyclopropyl-2-phenyl-1,4,5,6,7,8-hexahydropyrrolo[3,2-c]azepine and 5.0 g. of triethylamine in 50 ml. of dry chloroform. The mixture is stirred at ambient temperature for 20 hours, washed with water, dried, and concentrated to provide 1-cyclopropyl-2-phenyl-5-acetyl-1,4,5,6,7,8-hexahydropyrrolo[3,2-c]azepine as an oil. The oil is treated according to the manipulative procedure described above in Example 2, to give crystals, m.p. 85°C. dec., of 1-cyclopropyl-2-phenyl-5-ethyl-1,4,5,6,7,8-hexahydropyrrolo[3,2-c]azepine oxalate.
