HCID 312751,4-DioxaneSolvent

Procedure

135 mg (0.297 mmol) of t-butyl 2-oxo-2-[4-(9H-thioxanthen-9-ylidene)-1-piperidinyl]ethylcarbamate was dissolved in 2 ml of dioxane. After adding 2 ml of 4 N hydrochloric acid/1,4-dioxane solution, they were stirred overnight. The obtained mixture was neutralized with saturated aqueous sodium hydrogencarbonate solution. After extracting with ethyl acetate twice and drying over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure. 2 ml of dichloromethane and then 2 ml of 4 N hydrochloric acid/1,4-dioxane solution were added to the residue. The resultant precipitates were taken by the filtration, washed with dichloromethane and air-dried. After further drying under reduced pressure, the title compound was obtained.
