Reaction Steps

A mixture of 4-nitronaphthol (741 mg, 3.92 mmol), (2-aminopyrimidin-4-yl)methanol (31) (700 mg, 3.92 mmol) and PPh3 (1233 mg, 4.70 mmol) in THF (20 mL) was cooled to −50° C. under nitrogen and was treated dropwise over 5 min with DIAD (996 μl, 4.70 mmol). After completion of the addition, the mixture was allowed to warm to RT and stirred for 1 hr. A yellow precipitate forms during this time. After stirring overnight, the volatiles were evaporated and the residue triturated from MeOH (50 mL). The pale yellow solid collected by filtration and washed with diethyl ether (50 mL) to give 4-((4-nitronaphthalen-1-yloxy)methyl)pyrimidin-2-amine (32) (1.1 g, 93%): m/z 297 (M+H)+ (ES+).
