Reaction Conditions

Reaction Steps

To a solution of 3-(imidazo[1,2-a]pyridin-8-ylmethyl)isobenzofuran-1(3H)-one (80 mg, 0.3 mmol) in DCM (6 mL) at −78° C., was added lithium triethyl borohydride (1M/THF, 0.3 mL) dropwise. The reaction mixture was stirred at −78° C. for 30 min, diluted with DCM (\; 10 mL), and quenched with MeOH (1 mL) and 5% HCl (2 mL). The mixture was warmed up to rt and stirred for 1 h. The solvents were removed and the residue was purified on RP-HPLC using CH3CN and water as eluent to give 3-(imidazo[1,2-a]pyridin-8-ylmethyl)-1,3-dihydroisobenzofuran-1-ol (20 mg, 25%). 1H NMR (400 MHz, CD3OD) δ=8.56 (t, 1H), 8.97 (d, 1H), 7.74 (s, 1H), 7.45-7.32 (m, 5H), 7.07-7.00 (m, 1H), 6.38-6.30 (m, 1H), 5.84-5.80 (m, 0.5H), 5.56 (dd, 0.5H), 3.69 (t, 0.5H), 3.65 (t, 0.5H), 3.26 (dd, 0.5H), 3.13 (dd, 0.5H). LRMS (M+H+) m/z 267.1.
