Sodium Bicarbonate → HCID 58155241, compound

Participants

Reaction Steps

A solution of (RS)-5-[5-(benzhydrylidene-amino)-2-fluoro-phenyl]-5-cyclopropyl-morpholine-3-thione (1.42 g, 3.3 mmol) in dioxane (15 ml) and 1 M HCl (5 ml) was stirred at room temperature for 30 minutes. The reaction mixture was poured on a saturated solution of sodium hydrogen-carbonate and extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered and evaporated at reduced pressure. The residue was purified by chromatography on silica gel using a 3:1-mixture of dichloromethane and ethyl acetate as the eluent. CH2Cl2/EtOAc 3:1. The (RS)-5-(5-amino-2-fluoro-phenyl)-5-cyclopropyl-morpholine-3-thione was obtained as a white solid (0.810 g, 92% of theory). Mass (calculated) C13H15FN2OS [266.338]; (found) [M+H]+=267.
