Reaction Steps

A solution of methyl 3-(4-bromoacetylphenyl)propionate (380 mg) in acetonitrile (4 ml) was added dropwise over 15 minutes to a stirred solution of 1-(4-pyridyl)piperazine (450 mg) in acetonitrile (10 ml) and the mixture stirred overnight. The mixture was then filtered and the filtrate concentrated in vacuo to give an oil. Purification by flash chromatography on silica eluting first with dichloromethane then 5% v/v methanol/dichloromethane gave a solid. Trituration with ether gave the title compound, 172 mg, as a solid: m.p. 141°-143° C.; NMR (d6DMSO) δ 8.15(2H,d), 7.92(2H,d), 7.37(2H,d), 6.83(2H,d), 3.89(2H,s), 3.59(3H,s), 3.37(4H,t), 2.93(2H,t), 2.69(2H,t), 2.65(4H,t); m/e 368(M+H)+ ; calculated for C21H25N3 O3.0.25H2O: C, 67.8; H, 6.9; N, 11.3. found: C, 67.8; H, 6.9; N, 11.1%.
