Procedure

(3S)-4-{2-Chloro-6-[(phenylsulfonyl)methyl]pyrimidin-4-yl}-3-methylmorpholine (3.2 g, 8.70 mmol) was dissolved in a solution of 18% DMF in a mixture of 7:3:2 dimethoxyethane:water:ethanol (36 mL). Tert-butyl [4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbamate (4.16 g, 13.05 mmol), 2M sodium carbonate solution (8 mL) and dichlorobis(triphenylphosphine) palladium catalyst (306 mg, 0.43 mmol) were then added and the reaction refluxed at 90° C. for 2 hours under a nitrogen atmosphere. The reaction was allowed to cool to room temp then partitioned between ethyl acetate (20 mL) and water (20 mL). The organics were dried over magnesium sulphate, filtered and concentrated in vacuo. The crude solid was chromatographed on silica, eluting with 0-30% ethyl acetate in DCM to give the desired material as a beige solid (3.1 g).
