Reaction Steps

[2-Chloro-6-[(3S)-3-methylmorpholin-4-yl]pyrimidin-4-yl]methanol (500 mg) was dissolved in an 18% DMF in a mixture of 7:3:2 DME:water:ethanol (10 mL). 3-(1,2-Oxazol-3-yl)-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]urea (811 mg) and 2M aqueous sodium carbonate solution (4 mL) were then added to the solution and the resultant mixture degassed for 5 min. Dichlorobis(triphenylphosphine) palladium catalyst (73 mg) was added and the solution refluxed at 90° C. for 7 h under nitrogen atmosphere. The reaction was allowed to cool then neutralised with concentrated hydrochloric acid and loaded directly onto a SCX-2 column (50 g), the column was washed with methanol and the product eluted with 7N ammonia in methanol. The material was further purified by chromatography on silica, eluting with 5% methanol in DCM, to give the desired material (318 mg) as a white solid.
