mixture of [2-[2-(2,4-difluorophenyl)ethyl]-4-oxo-1(4H)-quinazolinyl]acetic acid (Int. C3) (100 mg, 1 equiv), methyl 2-methyl-2-[4-({[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]propanoate (Int. B1) (130 mg, 1.03 equiv), DIPEA (0.1 ml, 2 equiv), acetonitrile (2 ml) and HATU (130 mg, 1.4 equiv) was stirred at room temperature for 1 h, then evaporated and redissolved in acetonitrile. Purification by reverse phase HPLC (Preparative Method B) gave methyl 2-[4-({[2-[2-(2,4-difluorophenyl)ethyl]-4-oxo-1(4H)-quinazolinyl]acetyl}{[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]-2-methylpropanoate (126 mg).
