1-Methylpiperazine → HCID 15053395, compound

Participants

Reaction Steps

A solution of 2.9 g (0.01 mole) of 3-(4-bromophenoxy)-1-azetidinecarbonyl chloride in 15 ml of tetrahydrofuran was treated while stirring with 1 g (0.01 mole) of 1-methylpiperazine and stirred for 2 hr. The paste-like slurry was diluted with water and the solid was collected by filtration (4 g, wet). Recrystallization from benzene/ligroin yielded 3.0 g of white crystalline product, m.p. 91°-95° C. The solid and 1.16 g of fumaric were dissolved in isopropanol by boiling until a clear solution was obtained. Upon cooling, the precipitated salt was collected by filtration to yield 3 g (63.8%) of fine white crystals, m.p. 197°-198° C.
