Versuchsvorschrift

A solution of (RS)-5-[3-(benzhydrylidene-amino)-phenyl]-5-methyl-morpholin-3-one (5.62 g, 15 mmol) in dioxane (75 ml) was cooled to 15° C. and treated dropwise with 1 N hydrochloric acid (18 ml). The reaction mixture was stirred at room temperature overnight. For the workup, the reaction mixture was evaporated at reduced pressure, and the residue was portioned between diethylether (120 ml) and 1 N hydrochloric acid (20 ml). The aqueous phase was separated and washed with diethylether (120 ml). This procedure was repeated twice. The combined aqueous layers were evaporated at reduced pressure, and 3.27 g (88% of theory) of (RS)-5-(3-amino-phenyl)-5-methyl-morpholin-3-one hydrochloride were obtained as a yellowish solid used in the next step without further purification. Mass (calculated) C11H15ClN2O2 [242.707]; (found) [M+H]+=207.
