Reaction Steps

Add 3 mg (0.01 mmol) trans-bis(dicyclohexylamine)palladium(II) acetate [T. Bin, J. Org. Chem. 2004, 69, 4330-4335] to a mixture of 100 mg (0.22 mmol) 6-{[6-bromo-5-(4-methoxyphenyl)furo[2,3-d]pyrimidin-4-yl]amino}hexanoic acid methyl ester, 47 mg (0.34 mmol) 4-fluorophenylboronic acid and 95 mg (0.45 mmol) potassium phosphate in 5 ml dioxan, and stir for 21 h at 80° C. After filtering off the solid, concentrate the filtrate by vacuum evaporation. Purify the residue by preparative RP-HPLC (gradient: water/acetonitrile). 59 mg (57% of theor.) of the desired product is obtained.
