実験手順

To a suspension of 3,4-dihydro-6-(3,4-dimethoxyphenyl)-1-ethyl-3-methyl-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone (11.3 g) in water (20 ml) was added conc. hydrochloric acid (3.1 ml) and the mixture was evaporated under reduced pressure. To the residue was added ethanol (20 ml) and evaporated under reduced pressure again. The residue was crystallized from a mixture of diisopropyl ether and methanol (1:1) to give 3,4-dihydro-6-(3,4-dimethoxyphenyl)-1-ethyl-3-methyl-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone hydrochloride (9.9 g).
