Analogous to the procedure used to prepare Example 5(b), 4-chloro-6-(4-trifluoromethylphenyl)pyrimidine, Example 5(a), (200 mg, 0.77 mmol) and 3-methylsulphonylaniline hydrochloride (80 mg, 0.39 mmol, Acros) afforded a crude reaction product mixture, which was partitioned between EtOAc (100 mL) and 1 N NaOH (50 mL). The organic layer was washed with 1 N NaOH (50 mL), water (50 mL), satd NaCl (20 mL), dried over Na2SO4, filtered and concentrated in vacuo. Purification by silica gel chromatography (9:1 CH2Cl2/EtOAc) provided the title product as a white solid. MS (ESI, pos. ion) m/z: 394 (M+1). MP: 204-205° C.
