Reaction Steps

The synthesis method shall be explained concretely, and in order, below. 4,6-dimorpholino-2-(4-phenylpiperazin-1-yl)pyrimidine (300 mg, 0.73 mmol) was dissolved in chloroform solution (5 ml), benzoyl peroxide (0.3 mg, 0.0014 mmol) and N-chlorosuccinimide (117 mg, 0.87 mmol) was added, and refluxed under heating for 1 hour. Water was added, and extraction was done with dichloromethane. After washing the organic layer with saturated saline, drying was done with MgSO4, and the solvent was distilled away under reduced pressure. Purification was done by silica gel chromatography (hexane:ethyl acetate=4:1), and 142 mg of 5-chloro-4,6-dimorpholino-2-(4-phenylpiperazin-1-yl)pyrimidine was obtained (yield 46%). The melting point measurement result, the MS measurement result, and the NMR data for the obtained Compound 130 are shown below.
