2,4-Bis-benzyloxy-5-isopropyl-6-(2,3,5-trimethyl-phenoxy)-pyrimidine → 5-Isopropyl-6-(2,3,5-trimethyl-phenoxy)-1H-pyrimidine-2,4-dione

Participants

Reaction Steps

2,4-Bis-benzyloxy-5-isopropyl-6-(2,3,5-trimethyl-phenoxy)-pyrimidine was dissolved in 6 mL ethyl acetate and 6 mL ethanol mixture. 10% Pd/C (52 mg) was added to the mixture. Then hydrogen balloon was applied. The reaction was stirred at room temperature for 40 minutes. The reaction crude was filtered through celite. The filtrate was concentrated down and purified (silica gel, 0-50% EtOAC/hexane) followed by reverse phase HPLC (MeCN/water) to give white solid (94 mg, 59%). LC-MS shows 289.1 (M+1). 1H NMR (300 MHz, CDCl3): δ 9.6 (br, 1H), 8.9 (br, 1H), 6.88 (s, 1H), 6.58 (s, 1H), 3.12 (m, 1H), 2.18 (s, 6H), 2.12 (s, 3H), 1.22 (d, 6H).
