The reaction mixture was shaken at 90° C. overnight. The resin was filtered and washed with DMF, water, MeOH, CH2Cl2, then dried. The resin was treated with 95% TFA/H2O for 1.5 h at room temperature. Filtration and evaporation under reduced pressure afforded 6-(3-hydroxyphenyl)-4-(1H-indazol-5-ylamino)-2-morpholin-4-ylpyrimidine-5-carboxylic acid.
