실험 절차

To a solution of crude 2-[3,5-bis(trifluoromethyl)phenyl]-N-[4-(4-fluoro-2-methylphenyl)-6-(octahydro-2H-pyrazino[1,2-a]pyrazin-2-yl)-3-pyridinyl]-N,2-dimethylpropanamide (D80, 100 mg, 0.16 mmol) in 5 mL of acetonitrile was added a 37% aqueous formaldehyde solution (24 μL, 0.32 mmol). The solution was stirred at room temperature for 30 min, and then sodium triacetoxyborohydride (50 mg, 0.24 mmol) was added and the reaction stirred at room temperature overnight. The solvent was evaporated and the residue dissolved in dichloromethane and extracted with water and brine. The product was purified by flash chromatography (silica, dichloromethane to dichloromethane: MeOH 95:5). Obtained 58 mg of the title compound.
