Participants

Reaction Steps

The synthesis method shall be explained concretely, and in order, below. A solution of 5-amino-2-(4-phenylpiperazin-1-yl)-4,6-dimorpholinopyrimidine (700 mg, 1.64 mmol), acetic anhydride (5 ml), and pyridine (a few drops) was agitated for 1 hour at 60 degrees Celsius. The deposited solid was captured by filtering, washed with ether, and 330 mg of 5-acetylamino-4,6-dimorpholino-2-(4-phenylpiperazin-1-yl)pyrimidine was obtained (43% yield). The melting point measurement result, the MS measurement result, and the NMR data for the obtained Compound 77 are shown below.
