Reaction Steps

A mixture of (R)-tert-butyl 1-(3-bromo-4-cyanophenylamino)-3-methoxypropan-2-ylcarbamate (150 mg, 0.39 mmol), 5-amino-3-methylisothiazole hydrochloride (76 mg, 0.51 mmol), BINAP (25 mg, 0.04 mmol), Pd(OAc)2 (18 mg, 0.08 mmol) and K2CO3 (188 mg, 1.37 mmol) p-dioxane (3 mL) was degassed with Ar, then was heated at 120° C. for 15 h. the mixture was filtered, filter cake was washed with EtOAc, and the filtrated was concentrated in vacuo to give (R)-tert-butyl 1-(4-cyano-3-(3-methylisothiazol-5-ylamino)phenylamino)-3-methoxypropan-2-ylcarbamate as crude oil.
