Reaction Steps

To a solution of 3,4-dihydro-1,3-dimethyl-6-(4-methoxy-3-nitrophenyl)-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone (0.94 g) in a mixture of methanol (20 ml) and conc. hydrochloric acid (0.4 ml) was added palladium on activated carbon (10%, 0.20 g). The mixture was stirred under hydrogen atmosphere (1 atm) for 2 hours, and filtered. The filtrate was poured into aqueous sodium bicarbonate, and extracted with chloroform. The organic layer was dried over sodium sulfate, and evaporated. The resulting mass was crystallized from ethanol, to give 3,4-dihydro-6-(3-amino-4-methoxyphenyl)-1,3-dimethyl-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone (0.63 g).
