Reaction Steps

(R)-1-(3-bromo-1-trityl-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-(1-phenylethyl)urea (36 mg, 0.060 mmol), 1-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (18.6 mg, 0.090 mmol), PdCl2(dppf)-CH2Cl2 adduct (7.3 mg, 8.96 μmol), 1,4-dioxane (0.6 mL) and Na2CO3 (0.08 mL, 0.160 mmol, 2M) were charged in a vial. The mixture was evacuated and purged with nitrogen six times and heated at 80° C. for 1 h. The mixture was diluted with EtOAc, washed with water, brine, dried (Na2SO4) and concentrated in vacuo to afford crude (R)-1-(3-(1-methyl-1H-pyrazol-3-yl)-1-trityl-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-(1-phenylethyl)urea, which was used as such in the next step. MS ESI calcd. For C38H34N7O [M+H]+ 604, found 604.
