To the solution of 2,4-dichloro-6-(2-(isopropylsulfonyl)phenylamino)pyrimidine-5-carbaldehyde (112.3 mg, 0.3 mmol) in THF (1.0 mL) was added phenylmagnesiumbromide (3.0 M in diethyl ether, 1.0 mL, 3.0 mmol) at 0° C. under argon atmosphere. After addition, the reaction mixture was slowly warmed to room temperature and further stirred overnight. To the reaction mixture was then added 2.0 mL of saturated aqueous NH4Cl at 0° C., dissolved in EtOAc (50 mL) and washed with H2O (10 mL) and brine (10 mL). The organic phase was dried over Na2SO4, concentrated in vacuo, and purified by silica gel chromatography (eluent: EtOAc in Hexanes: 0 to 33%) to afford (2,4-dichloro-6-(2-(isopropylsulfonyl)phenylamino)pyrimidin-5-yl)(phenyl)methanol as a colorless oil. MS (ES+): 452.0 (MH+).
