실험 절차

To a cooled solution of CH2Cl2 (10 mL) containing diisopropylethylamine (0.275 mL, 2.0 mmol) and [3,5-dimethylbenzoyl]-3-(3,4-dichlorophenyl)piperazine (Enantiomer B) (Example 4) (305 mg, 0.84 mmol) was added chloropropionyl chloride (0.075 mL, 0.8 mmol). The reaction mixture was allowed to warm to room temperature. After 20 minutes, (1S,4S)-2-benzyl-2,5-diazabicyclo(2.2.1)heptane 2HBr (297 mg, 0.85 mmol) and diisopropylethylamine (0.275 mL, 2.0 mmol) were added and the mixture was left over night, after which the reaction mixture was concentrated. The product was purified by flash chromatography on flash grade silica gel, eluting with 30:1:0.1 CH2Cl2 /MeOH/NH3 to give a foamy solid (140 mg, 0.23 mmol, 29%), High Res. MS:[M+1]+ calcd. for C34H39Cl2N4O2 605.2450; Found, 605.2465.
