Participants

Reaction Steps

Add 3 mg (0.01 mmol) trans-bis(dicyclohexylamin)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, 37 mg (0.27 mmol) 4-fluorophenylboronic acid and 95 mg (0.45 mmol) potassium phosphate in 5 ml ethanol, and stir, firstly for 16 h at RT and then for 3 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). 28 mg (26% of theor.) of the desired product is obtained.
