Procedure
A 200 mg portion of 2-(4-methyl-1-homopiperazinyl)-benzoxazole was dissolved in 5 ml of tetrahydrofuran (THF). Under cooling with ice, 0.064 ml of methyl iodide was added to the thus prepared solution, and the reaction was carried out for 1 hour at the same temperature and then for 2 hours at room temperature. The reaction solution was concentrated under a reduced pressure, and 5 ml of acetone was added to the resulting residue. The precipitate thus formed was collected by filtration, washed with acetone and then dried to obtain 320 mg of the title compound.
