実験手順
To a N2 purged round bottom flask was added benzyl 3-(3-(3,6-dihydro-2H-pyran-4-yl)pyrazin-2-yloxy)azetidine-1-carboxylate (see PREPARATION P28.2; 490 mg, 1.334 mmol), pearlman's catalyst (37.5 mg, 0.267 mmol) and EtOH (10 mL). A balloon of H2 was placed atop the round bottom flask. After 20 hours, the reaction was filtered through CELITE® and the cake was washed with EtOAc. The filtrate was concentrated in vacuo to give 2-(azetidin-3-yloxy)-3-(tetrahydro-2H-pyran-4-yl)pyrazine (240 mg, 1.020 mmol, 76% yield), as a tan residue. MS (ESI) m/z 236.1 (MH+).
