Reaction Steps

A solution of 2-(cyclohexylmethyl)-5-(3-fluoro-4-(1-(4-methoxybenzyl)-3-(4-(morpholine-4-carbonyl)phenyl)-1H-pyrazolo[3,4-b]pyridin-4-yloxy)phenyl)-3-methylpyrimidin-4(3H)-one (0.027 g, 0.0363 mmol) in TFA (1 mL) was stirred at 60° C. for 3 minutes and then at ambient temperature overnight. The reaction mixture was concentrated in vacuo and the residue was partitioned between EtOAc and saturated NaHCO3. The layers were separated and the aqueous layer was re-extracted with EtOAc (1×). The combined EtOAc layers were dried over Na2SO4, filtered and concentrated. The crude product was purified by flash column chromatography, eluting with 10:1 CH2Cl2/MeOH. The product was obtained (17.3 mg; 76%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 8.41 (d, 1H), 8.27 (s, 1H), 8.08 (d, 2H), 7.89 (m, 1H), 7.71 (m, 1H), 7.59-7.49 (m, 4H), 6.43 (d, 1H), 3.60 (m, 8H), 3.53 (s, 3H), 2.73 (d, 2H), 1.96 (m, 1H), 1.82-1.59 (m, 5H), 1.34-0.99 (m, 5H). LRMS (APCI pos) m/e 623 (M+1).
