Reaction Steps
In a 50 mL round-bottomed flask N-{6-[(2,6-dimethylphenyl)oxy]-3-pyridinyl}-2-methylalaninamide (Intermediate 80, 144.4 mg) was dissolved in dichloromethane (5 mL) to give a pale yellow solution. The reaction mixture was cooled at 0° C. N,N-dimethyl-4-pyridinamine (27.7 mg, 0.227 mmol), triethylamine (0.158 mL, 1.134 mmol) and triphosgene (67.3 mg, 0.227 mmol) were added. The reaction mixture was stirred at 0° C. After 20 min, the solvent was evaporated under vacuum to afford a yellow solid which was purified via silica gel chromatography (Biotage system, 10 g SNAP column) using as eluent a gradient Cyclohexane/EtOAc from 2:1 to 1:3 in 20 CV; then 1:3 for 5 CV. The collected fractions afforded the title compound as a white solid (139.7 mg).
