Participants

Reaction Steps

In a 8 mL vial N-{[(1,1-dimethylethyl)oxy]carbonyl}-2-methylalanine (204 mg, 1.003 mmol) and N-ethyl-N-(1-methylethyl)-2-propanamine (0.219 mL, 1.253 mmol) were dissolved in N,N-Dimethylformamide (4 mL) to give a pale yellow solution. N-[(dimethylamino)(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yloxy)methylidene]-N-methylmethanaminium hexafluorophosphate (381 mg, 1.003 mmol) was added. The reaction mixture became bright yellow and was stirred at room temperature for 15 minutes. 6-[(2,6-dimethylphenyl)oxy]-3-pyridinamine (Intermediate 42, 223.8 mg) was added and the reaction mixture was warmed at 60° C. After 4 hours, the reaction was complete. The solvent was evaporated under vacuum using the Genevac affording a dark brown oil which was purified by silica gel chromatography (Biotage system, 25 g SNAP column) using as eluents a gradient Cyclohexane/EtOAc from 3:1 to 1:1 in 10 CV; then 1:1 for 5 CV. The collected fractions afforded the title compound as a pale yellow solid (202.1 mg).
