Методика

1-(2-Methoxy-4-(1-ethenylsulfonyl-4-piperidyloxy)phenylacetyl)-4-(2-methylphenyl)piperazine-2-carboxamide (69 mg, 0.12 mmol) was dissolved in methanol (4 ml), treated with cyclopropylamine (0.0072 ml, 10 mg, 0.18 mmol), and stirred at ambient temperature under nitrogen for 18 hours. An additional 0.014 ml of cyclopropylamine was added and the mixture stirred another 72 hours at ambient temperature. The reaction was concentrated in vacuo and the residue was chromatographed on silica gel eluted with 4% methanol in methylene chloride. The combined product fractions were evaporated to dryness in vacuo. The residue was reconcentrated from ether to give 1-(2-methoxy-4-(1-(2-(N-cyclopropylamino)ethylsulfonyl)-4-piperidyloxy)phenylacetyl)-4-(2-methylphenyl)piperazine-2-carboxamide: mp 69°-110° C.
