Diethyl allylmalonate → HCID 178439779, compound

Participants

Reaction Conditions

Reaction Steps

Sodium metal (4.5 g) was added slowly into ethanol (100 mL) in a 500 mL round bottom flask under nitrogen atmosphere. The reaction mixture was stirred at room temperature until all the sodium metal dissolved, before being cooled to 0° C. Diethyl 2-allylmalonate (12 g) was added into the reaction mixture, followed by formamidine acetate (6.24 g) under nitrogen atmosphere at 0° C. The reaction was stirred at room temperature for 24 hours under nitrogen atmosphere, before being quenched by acetic acid (20 mL), followed by water (100 mL). The white precipitate was filtered, washed with water (4×50 mL), methanol (2×50 mL) and dried under vacuum to afford 5-allylpyrimidine-4,6-diol (4 g) as white solid. 1H NMR (DMSO-d6): δ 2.96 (d, 2H), 4.85 (dd, 1H), 4.91 (dd, 1H), 5.76 (dd, 1H), 7.89 (s, 1H), 11.64 (bs, 2H).
