145
4-(3-(te/t-butoxycarbonylamino)-1 -(isoquinolin-6-ylamino)-1 -oxopropan-2- yl)benzyl 2,4-dimethylbenzoate (E145) was prepared E139 according to the below: To 2,4-dimethylbenzoic acid in pyridine was added EDC, DMAP, and te/t-butyl 2-(4- (hydroxymethyl)phenyl)-3-(isoquinolin-6-ylamino)-3-oxopropylcarbamate (E139), and the solution was capped and stirred overnight. The mixture was poured into EtOAc/NaHCO3(Sat) and the aqueous layer was further extracted with EtOAc. The organics were dried (MgSO4), filtered, and evaporated. Column chromatography (SiO2, 0-5% MeOH/CH2CI2 gradient) gave pure 4-(3-(te/t-butoxycarbonylamino)-1 -(isoquinolin-6-ylamino)-1 -oxopropan-2- yl)benzyl 2,4-dimethylbenzoate (E145).
