Procedure

A 30 mg portion of 6-amino-5-chloro-2-(4-methyl-1-piperazinyl)benzoxazole was dissolved in 20 ml of anhydrous toluene, and the solution was mixed with 1 ml of benzaldehyde and heated under reflux for 6 hours. The solvent was concentrated under a reduced pressure, the residual oily matter was mixed with hexane and then the thus formed precipitate was collected by filtration to obtain the title compound (24 mg) in white color.
