Reaction Steps

To a solution of (2,6-dichloro-pyrimidin-4-yl)-methyl-(tetrahydro-pyran-4-yl)amine (0.4 g, 1.5 mmol) in degassed dioxane and H2O (4/1, 25 mL) was added Na2CO3 (315 mg, 3.0 mmol); Pd(PPh3)4 (86 mg, 0.075 mmol) and {2-(tert-Butyl-dimethyl-silanyloxy)-3-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenoxy]-propyl}-methyl-carbamic acid tert-butyl ester (703 mg, 1.35 mmol). The system was purged with N2 stream and the mixture was stirred at 100° C. for 2 h., cooled to room temperature, diluted with water (50 mL) and extracted with EtOAc (50 mL×2). The organic layers were combined, dried over Na2SO4, filtered and concentrated. The residue was purified by preparative HPLC to give [2-(tert-Butyl-dimethyl-silanyloxy)-3-(3-{4-chloro-6-[methyl-(tetrahydro-pyran-4-yl)-amino]-pyrimidin-2-yl}-phenoxy)-propyl]-methyl-carbamic acid tert-butyl ester (373 mg, 40% yield) as major product. ESI-LCMS (m/z): 411.2 [M+1]+along with the minor product [2-(tert-Butyl-dimethyl-silanyloxy)-3-(3-{2-chloro-6-[methyl-(tetrahydro-pyran-4-yl)-amino]-pyrimidin-4-yl}-phenoxy)-propyl]-methyl-carbamic acid tert-butyl ester (140 mg, 15% yield). ESI-LCMS (m/z): 411.2 [M+1]+.
