実験手順

A suspension of (R)-tert-butyl 2-(4-(diphenylmethyleneamino)phenyl)morpholine-4-carboxylate (6 g, 13.6 mmol), ammonium formate (12.8 g, 203 mmol) and Pd/C5% (721 mg, 0.339 mmol) in methanol (103 ml) was stirred at 60° C. for 2 h. The reaction mixture was filtered and concentrated. The residue was dissolved in ethyl acetate and water. The organic phase was extracted twice with 0.5M HCl. The combined aqueous phases were basified with 2M-NaOH and extracted twice with DCM. The organic phases were dried over magnesium sulfate, filtered and dried in vacuo, to yield 3.04 g off-white solid. MS (ISP): 279.1 ([M+H]+).
