7% | Hydrochloric acid (2M, 207 mL, 414 mmol) was added to 4-(dimethoxymethyl)pyrimidin-2-amine (68) (WO 2007/096764) (14.0 g, 83 mmol) and the mixture heated at 48° C. for 16 hr. The mixture was cooled to RT and was neutralized with solid Na2CO3 which produced a precipitate at pH 7. The suspension was diluted with EtOAc (300 mL) and the solid removed by filtration. The organic layer was separated and the aqueous layer was extracted with 1percent MeOH in THF (4×300 mL). The organics were combined, dried and then evaporated in vacuo.

67% | In acetone; at 70℃;Inert atmosphere; | Compounds 4-(dimethoxymethyl)pyrimidin-2-amine 68 8b (1.00 g, 5.65 mmol), 70 iodomethane (2.80 g, 19.77 mmol) and 71 acetone (30 mL) were mixed. This mixture were stirred for 16 h at 70 C., cooled to room temperature, and filtered. The solid was mixed with 10% 67 sodium hydroxide (8 mL), stirred for 0.5 h at 80 C., and cooled to room temperature. This mixture was quenched with 250 mL of 72 ice water, extracted with dichloromethane (50 mL×2), and the organic phase was washed with saturated brine (50 mL×2). The organic phase was dried over anhydrous sodium sulfate, filtered to remove the drying agent, and subjected to exsolution under reduced pressure, to obtain the target 73 product 8c 4-(dimethoxymethyl)-N-methylpyrimidin-2-amine 8c (0.70 g, yellow oil), at a yield of 67%.
