Participants

Reaction Steps

The synthesis method shall be explained concretely, and in order, below. A mixed solution of 2-[2-(4-methoxyphenyl)vinyl]-4,6-dimorpholino-5-nitropyrimidine (1.35 g, 3.16 mmol), zinc dust (6.19 g, 94.8 mmol), and calcium chloride (224 mg, 2.02 mmol) in acetonitrile (80 ml) and water (20 ml) was refluxed under heating for 1 hour. The undissolved matter was separated out by celite filtering, the filtrate was distilled away under reduced pressure, water was added to the residue, the precipitated crystals were taken out by filtering, and 5-amino-2-[2-(4-methoxyphenyl)vinyl]-4,6-dimorpholinopyrimidine (940 mg, yield 75%) was obtained. The melting point measurement result, the MS measurement result, and the NMR data for the obtained Compound 131 are shown below.
