Reaction Steps

A thick-walled microwave bottle equipped with a stirbar was charged with MeOH (2.0 equiv) and NMP (20 volume equivalents). To the resulting solution was added NaH (2.0 equiv), resulting in gas evolution. (S)-6-Bromo-1-(1-phenylethyl)-1H-imidazo[4,5-b]pyrazin-2-ol (1.0 equiv) was then added to the reaction, and the resulting mixture was immediately fitted with a septum and cap and heated to 200° C. in a microwave for 30 min. The reaction was then diluted with EtOAc, washed twice with saturated aq. NaHCO3 and once with brine. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. Reverse-phase preparative HPLC provided the title compound (29%) as a white solid. LCMS m/z (APCI)=271.1 (M+H).
