Reaction Steps

The starting 2-[3,5-bis(trifluoromethyl)phenyl]-N-(4-(4-fluoro-2-methylphenyl)-6-{[(2S)-2-pyrrolidinylmethyl]amino}-3-pyridinyl)-N,2-dimethylpropanamide (D62, 38 mg, 0.064 mmol) was dissolved in 1 mL of anhydrous dichloromethane and treated with triethylamine (20 μL, 0.143 mmol). The solution was brought to 0° C. and triphosgene (10 mg, 0.034 mmol) was added. The reaction was stirred at 0° C. for 15 min, then brought to room temperature. After 24 h, the reaction was diluted with dichloromethane (10 mL) and extracted with brine. The organics were collected and the solvent removed. The product was isolated by flash chromatography (silica, cyclohexane: EtOAc 80:20 to EtOAc). Thus were obtained 8 mg of the target compound.
