To a solution of 4-dimethoxymethyl-2-methyl-pyrimidine (10 g) from I.1.1 in methanol (100 mL) was added 8.2 g of hydroxylamine hydrochloride and 10% HCl and the reaction mixture was heated under reflux for 2 h. After cooling to room temperature, the pH was adjusted to 8 using solid sodium carbonate. The mixture was stirred for 30 minutes. The solid was sucked off, dried at 50° C. under reduced pressure to yield 6.0 g (73%) of the title compound as white solid.
