Procedure
Crude (S)-1-(2-((tert-butyldimethylsilyl)oxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-((1-methyl-1H-pyrazol-5-yl)amino)pyrimidin-4-yl)pyridin-2(1H-one (48 mg) was dissolved in ethyl acetate (4 mL) and treated dropwise slowly (over 2 minutes) with an ethyl acetate solution (1.0 mL, which had been saturated with HCl gas). The reaction stirred at room temperature for 15 minutes, after which time LCMS indicated complete consumption of the starting material. The reaction mixture was concentrated to an oily residue and purified by prep RP HPLC to yield (S)-1-(1-(4-chloro-3-fluorophenyl)-2-hydroxyethyl)-4-(2-((1-methyl-1H-pyrazol-5-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (20.8 mg, 54.6% yield) as a lyophilized powder. 1H NMR (400 MHz, (CD3)2SO) δ 9.58 (s, 1H), 8.60 (d, J=5.1 Hz, 1H), 7.91 (t, J=9.0 Hz, 1H), 7.58 (t, J=8.1 Hz, 1H), 7.52-7.41 (m, 2H), 7.37 (d, J=1.8 Hz, 1H), 7.14 (dd, J=10.7, 5.1 Hz 2H), 6.86 (dd, J=7.3, 1.8 Hz, 1H), 6.27 (d, J=1.7 Hz, 1H), 5.97 (dd, J=7.7, 5.7 Hz, 1H), 5.31 (t, J=5.2 Hz, 1H), 4.15 (m, 1H), 4.10-3.95 (m, 1H), 3.69 (s, 3H); LCMS m/z 441 (M+H)+.
