Reaction Steps

Methyl 2-(4-(3-(tert-butoxycarbonylamino)-1-(isoquinolin-6-ylamino)-1-oxopropan-2-yl)phenoxy)acetate (E250) was prepared from E249 according to the scheme in FIG. 14. To tert-butyl 2-(4-hydroxyphenyl)-3-(isoquinolin-6-ylamino)-3-oxopropylcarbamate (E249) in DMF cooled to −35° C. was added NaH, and the solution was stirred at −35° C. for 30 min. Then, methyl bromoacetate was added and the solution was warmed and stirred at 0° C. for 1 h. The solution was poured into NaHCO3(sat)/EtOAc and further extracted with EtOAc. The combined organics were dried (Na2SO4), filtered, and evaporated. Column chromatography (SiO2, 3-4% MeOH/CH2Cl2) gave pure methyl 2-(4-(3-(tert-butoxycarbonylamino)-1-(isoquinolin-6-ylamino)-1-oxopropan-2-yl)phenoxy)acetate (E250).
