To a 10° C. solution of 1-(isoquinolin-5-yl)ethanol (530 mg, 3.0 mmol) in DCM (10 mL) was added Dess-Martin periodinane (1.9 g, 4.0 mmol) under a N2 atmosphere. The reaction mixture was stirred for 16 h at room temperature and then quenched with saturated NaHCO3 solution (5 mL). The organic layer was separated, washed with water and brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to obtain the crude product. The crude material was purified via silica gel column chromatography using 20% ethyl acetate in hexanes to afford 1-(isoquinolin-5-yl)ethanone (500 mg, 95.4%) as an off-white solid.
