Participants

Reaction Steps

To a mixture of 7-bromo-3-methyl-9-pentyl-6,9-dihydro-5h-[1,2,4]triazolo[4,3-a]purin-5-one (100 mg, 0.30 mmol), phenylboronic acid (39.5 mg, 0.32 mmol), sodium carbonate (100 mg, 0.94 mmol) in water (2 ml) and 1,2-dimethoxyethane (20 ml) was added tetrakis(triphenylphosphine)-palladium(0) (200 mg, 0.10 mmol). The mixture was heated to reflux overnight. The reaction mixture was diluted with water and extracted with ethyl acetate three times. The combined organic layers were dried with sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by preparative LCMS to yield the desired product (16 mg, 16%). 1HNMR (400 MHz, CD3OD): δ 8.06 (m, 2H), 7.49 (m, 3H), 4.38 (t, J=8.0 Hz, 2H), 2.83 (s, 3H), 1.95 (m, 2H), 1.42 (m, 4H), 0.92 (m, 3H). LCMS calculated for C18H21N6O(M+H): 337.2; found 337.2.
