Triethylamine → HCID 18697984, compound

Participants

Reaction Steps

2-Methyl-4-chloro-pyrimidine (0.34 g) was added to a suspension of 1-(4-bromophenylsulphonyl)-4-(1-piperazinylcarbonyl)piperidine (1.0 g) in ethanol (10 ml) and 1(triethylamine (0.5 ml). The reaction was heated under reflux for 2 hours, cooled and the solvent removed by evaporation. The reaction mixture was purified by filtration column chromatography (silica, gradient elution dichloromethane to 10% methanol in dichloromethane) to give 1-(4-bromophenylsulphonyl)-4-[1-(2-methylpyrimidin-4-yl)piperazin-4-ylcarbonyl]piperidine as a solid (0.82 g) mpt 239-240° C.; NMR (CDCl3) 1.75-2.0 (m, 5H), 2.5 (m, 2H), 3.45-3.8 (m, 10H), 6.3 (m, 1H), 7.65 (m, 4H), 8.2 (m, 1H).
