Reaction Steps

A stirred mixture of 8.3 g (0.056 mol) of 5-(2-chloroethyl)-2-oxazolidinone, 11 g (0.056 mol) of 1-(2-chlorophenyl)piperazine and 7.7 g (0.056 mol) of potassium carbonate in 150 ml of 2-propanol was heated at reflux temperature for 18 h. The mixture was filtered and the filtrate concentrated at reduced pressure. The residue was dissolved in 2-propanol and treated with a solution of 6.9 g (0.0595 mol) of maleic acid in warm methanol. The resulting maleic acid salt was collected and recrystallized several times from a 2-butanone/methanol mixture to obtain 5.8 g (25%) of solid, mp 166°-168.5° C.
