Potassium Carbonate → 3-[5-Cyclopropyl-3-(2,6-difluoro-pyridin-4-ylmethyl)-2,6-dioxo 1,2,3,6tetrahydro-pyrimidine-4-carbonyl]-5-methyl-benzonitrile

Participants

Reaction Steps

3-(5-Cyclopropyl-2,6-dioxo-1,2,3,6-tetrahydro-pyrimidine-4-carbonyl)-5-methyl-benzonitrile (10 mg, 0.034 mmol) was dissolved in 0.5 mL DMF. Potassium carbonate (4.7 mg, 1 eq.) and 4-bromomethyl-2,6-difluoro-pyridine (7 mg, 1 eq.) were added to the reaction, followed by lithium iodide (4.5 mg, 1 eq.) The reaction was stirred at room temperature overnight. Ethyl acetate was added to the reaction mixture, followed by washing with brine. The organic layer was concentrated down and purified by reversed phase HPLC (MeCN/water) to give white powder (1.2 mg, 9%). LC-MS shows 420.9 (M−1). 1H NMR (300 MHz, CD3OD): δ 8.40 (s, 1H), 7.97 (s, 1H), 7.79 (s, 1H), 7.76 (s, 1H), 6.58 (s, 2H), 4.85 (s, 2H), 2.44 (s, 3H), 1.01 (m, 1H), 0.72 (m, 3H), 0.43 (m, 1H).
