Reaction Steps

To a solution of 251 (30.8 mg, 0.134 mmol) in NMP (1.4 mL) a suspension of KH in mineral oil (35%, 31 mL, 0.268 mmol) was added in one portion. The mixture was stirred at room temperature overnight and partitioned between EtOAc and water. The organic phase was collected, dried over anhydrous Na2SO4 and concentrated. The residue was purified by flash chromatography, eluent EtOAc/hexane (1:2) to afford title compound affording 252 (22.7 mg, 74% yield). MS (m/z): 230.1 (100%) 232.1 (33%) (M+1).
