Versuchsvorschrift

2-Chloro-4-[(3S)-3-methylmorpholin-4-yl]-6-(methylsulfonylmethyl)pyrimidine (1.01 g, 3.30 mmol) was dissolved in 18% DMF in 7:3:2 dimethoxy ethane:water:ethanol (7 mL). N-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (1.00 g, 4.29 mmol), 2M sodium carbonate solution (4 mL) and dichlorobis(triphenylphosphine) palladium (116 mg, 0.16 mmol) were added to the solution. The reaction was refluxed at 90° C. for 3 hours under nitrogen atmosphere then the mixture allowed to cool and partitioned ethyl acetate (30 mL) and water (30 mL). The organic layer was dried over magnesium sulphate, filtered and evaporated to dryness. The brown oil was dissolved in DCM and filtered to remove insoluble material then the filtrate chromatographed on silica, eluting with 0-4% methanol in DCM, to give the desired product as a yellow foam (1.12 g, 90%)
