Triethylamine → 5-phenyl-1-(4-{(1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hex-3-yl}butyl)-2(1H)-pyrimidinone

Temperatur

100 °C

To a solution of (1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hexane (52 mg, 0.23 mmol, prepared with a similar procedure to that reported in WO 2005080382) in N,N-dimethylformamide (DMF) (3 ml) were added at room temperature 1-(4-chlorobutyl)-5-phenyl-2(1H)-pyrimidinone (Prep51, 60.1 mg, 0.23 mmol, D1) and triethylamine (0.064 ml, 0.46 mmol). The reaction mixture was heated at 100° C. for 24 hours, then passed through a SCX cartridge (10 g) (eluting with methanol followed by 2N ammonia solution in methanol). The crude obtained was then purified by column chromatography on silica gel eluting with DCM/methanol 96/4. After evaporation of the solvent the compound recovered (20 mg, 0.044 mmol) was dissolved in DCM (1 ml) and treated with HCl (1.1 eq of a 1.25 M solution in methanol, 0.048 mmol). The resulting mixture was stirred at room temperature for 0.5 hour. Evaporation of the solvent and trituration with diethyl ether (2×3 ml) gave the hydrochloride salt of the title compound. The recovered material was passed through SCX (2 g) cartridge (eluting with methanol followed by 2N ammonia solution in methanol) to recover (6 mg, 0.013 mmol) of the title compound.
