To a suspension of 6-(N-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)methyl sulfonamido)-2-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide (0.308 g, 0.596 g) in 85:15 DCM/MeOH (5 mL) was added 4M HCl in dioxane (1.0 mL). After 1 hour, water (0.5 mL) was added and a solid formed. After 1 hour, the solid was filtered and washed successively twice with 2 mL DCM, twice with 1 mL MeOH, once with 3 mL MeOH, and twice with 1 mL DCM. The solid was dried under vacuum at 40° C. to give 6-(N-(2,3-dihydroxypropyl)methylsulfonamido)-2-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide as a white powder (0.200 g, 0.420 mmol, 70% yield). 1H NMR (400 MHz, DMSO-d6): 8.63-8.54 (3H, m), 8.01 (1H, s), 7.84 (1H, s), 7.33-7.26 (2H, m), 7.23-7.17 (2H, m), 7.09 (2H, d, J=8.8 Hz), 5.08 (1H, d, J=5.5 Hz), 4.80 (1H, t, J=5.7 Hz), 4.31-4.24 (1H, m), 4.05-3.96 (1H, m), 3.86-3.77 (1H, m), 3.54 (3H, s), 3.45-3.35 (2H, m). LC/MS: m/z=477.1 [M+H]+.
