Reaction Steps

To a slurry of (2S)-1-[(1R,2R)-5-bromo-2-ethoxy-2,3-dihydro-1H-inden-1-yl]-2-methyl-4-(4-methylpiperidin-4-yl)piperazine trihydrochloride (50 mg, 0.0916 mmol) in methylene chloride (6 mL) were added 4,6-dimethyl-pyrimidine-5-carboxylic acid (27.88 mg, 0.183 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (21.07 mg, 0.11 mmol), 1-hydroxybenzotriazole (13.62 mg, 0.101 mmol) and triethylamine (0.0894 mL, 0.641 mmol). The reaction mixture was stirred at room temperature overnight. Direct chromatography on silica gel with 10% MeOH/EtOAc (1% NH4OH) afforded the desired product (42 mg, 80%). LC-MS [M+1]=570.10; 572.05.
