Participants

Reaction Steps

A solution of 13.25 ml (0.0581 m) of 25% sodium methoxide in methanol was added dropwise to a mixture of 20 g (0.063 m) of 2-chloro-4-benzyloxy-5-[(6-methyl-3-pyridinyl)-methyl]-pyrimidine prepared as in Example 3 and 250 ml of toluene. The mixture is allowed to stir overnight at room temperature then washed with water and evaporated. The residual oil which was 2-methoxy-4-benzyloxy-5-[(6-methyl-3-pyridinyl)-methyl]-pyrimidine was dissolved in ethanol and hydrogenated over 0.6 g of 10% palladium on charcoal. After hydrogen absorption, the reaction mixture was filtered, concentrated to an oil which was taken up in methylene dichloride. Ether was added to give 8.4 g (59%) of 2-methoxy-5-[(6-methyl-3-pyridinyl)-methyl]-4-(1H)-pyrimidinone, m.p. 145°-147°.
