Reaction Steps

Triethylamine (1.05 mL, 7.53 mmol) was added to a mixture of N2-o-tolylpyridine-2,3-diamine (500 mg, 2.51 mmol), (S)-2-tertbutoxycarbonylaminopropionic acid (520 mg, 2.76 mmol), HOAt (380 mg, 2.76 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (530 mg, 2.76 mmol) in anhydrous DCM (20 mL) at 0° C. under a nitrogen atmosphere. The reaction mixture was stirred at 0° C. for 10 min and then slowly warmed to RT. Stirring at RT was continued for 16 h. The resulting mixture was partitioned between DCM and a saturated aqueous solution of NaHCO3. The aqueous phase was further extracted with DCM and the combined organic fractions were washed with water, dried (Na2SO4) and concentrated in vacuo to afford the title compound. The crude material was used without further purification in the following step. Yield assumed to be quantitative. LCMS (Method J): RT 2.19 min [M+H]+ 371.1.
