1-Methylhomopiperazine → 1-[2-(2-Imidazolylmethyl)phenylcarbamoyl]-4-methylhomopiperazine

Participants

Reaction Steps

To a suspension of 0.76 g of 11H-imidazo[1,2-c][1,3]-benzodiazepin-5-(6H)-one in 9 ml of methylene chloride is added at once 0.41 g of N-methylhomopiperazine and the mixture is stirred at room temperature for 24 hours. The reaction mixture is filtered and the filtrate is evaporated to dryness. Recrystallization of the residue from methylene chloride-ether gave 1-[2-(2-imidazolylmethyl)phenylcarbamoyl]-4-methylhomopiperazine, the compound of formula VI wherein R1, R2, R4 -R7 are hydrogen, CnH2n is (CH2)3, R3 is methyl and Z is oxygen, melting at 139°-143°.
