Procedure

In a 50 mL round-bottomed flask N1-{6-[(2-ethylphenyl)oxy]-3-pyridinyl}-2-methylalaninamide (Intermediate 78, 67.1 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 (13.28 mg, 0.109 mmol), triethylamine (0.076 mL, 0.544 mmol) and triphosgene (32.3 mg, 0.109 mmol) were added. The reaction mixture was stirred at 0° C. After 20 minutes, the reaction mixture was evaporated under vacuum to afford a yellow solid which was purified by silica gel chromatography (Biotage system, 10 g SNAP column) eluting with 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 (60.9 mg).
