Reaction Steps
Piperazine (149.2 g, 8 mol equiv) was heated to a melt and 1-(t-butoxycarbonyl)-3-methanesulphonyloxyazetidine (see (International Patent Application Publication No. WO93/19059) (54.5 g, 217 mmol)was then added. The mixture was heated at 115° C. for 24 hours, then cooled and the excess piperazine removed in vacuo. The residue was purified by flash chromatography (silica, methanol:dichloromethane, 1:19) to give the title compound (51 g).
