Reaction Steps

A solution of 2-(1-amino-5-fluoro-1H-indol-3-yl)-2-methyl-propionic acid methyl ester (0.85 mmol) and 4-methyl-2-pyridin-2-yl-pyrimidine-5-carboxylic acid (201 mg, 0.935 mmol) in DMF (8.5 mL) is stirred at 40° C. for 0.5 h. The mixture is treated with DMTMM (246 mg, 0.89 mmol) and stirred at 60° C. for 1 h. The mixture is concentrated in vacuo, diluted with saturated aqueous Na2CO3 (20 mL), and extracted with EtOAc (3×20 mL). The combined organic layer is dried (Na2SO4), filtered and concentrated in vacuo to afford 2-{5-fluoro-1-[(4-methyl-2-pyridin-2-yl-pyrimidine-5-carbonyl)-amino]-1H-indol-3-yl}-2-methyl-propionic acid methyl ester, which is used in the next step without further purification.
