Participants

Reaction Steps

To a solution of 5,6-difluoro-2-(5-fluoropyridin-3-yl)-1H-benzo[d]imidazol-1-ol 0.15 g, 0.0003 mol) in THF (3.5 ml) was added NaH (0.045 g, 0.0011 mol) at room temperature. After stirring for 5 min at room temperature MeI (0.04 mL, 0.00059 mol) was added in one shot and further stirred for another 1 hr. After the consumption of the starting material (by TLC) the reaction mixture was washed with H2O and extracted with EtOAc (2×30 mL). The organic phase was dried and concentrated under vacuum. The crude was washed with Hexanes and further purified by chromatography (5-40% EtOAc/Hexanes) to give the desired compound 372 as a white solid. 1H NMR (400 MHz, DMSO-d6), δ: 9.28 (s, 1H), 8.62 (s, 1H), 8.24 (s, 1H), 7.58 (s, 1H), 7.32 (s, 1H), 4.06 (s, 3H). MS (M+1): 280, Purity 99.67%.
