Pyrimidine-2(1H)-thiones and their corresponding dihydroderivatives were treated with Raney nickel to afford respectively three types of dihydropyrimidine isomers, which reacted with malachite green in similar rate constants to 1-benzyl-1,4-dihydronicotinamide.

, p. 1799 - 1802 (2007/10/02)
N-Substituted pyrimidine-2(1H)-thiones (1), 3,4- (2), and 3,6-dihydropyrimidine-2(1H)-thiones (3) were easily desulphurized with Raney nickel to give N-substituted 1,2- (4), 1,4- (5), and 1,6-dihydropyrimidines (6), respectively.Further, the properties of
