Reaction Steps

A mixture of 1,1-dimethylethyl 2-methyl-2-[4-({[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]propanoate (Int. B4) (1 equiv), [2-[2-(2,3-difluorophenyl)ethyl]-4-oxo-1(4H)-quinazolinyl]acetic acid (Int. C1) (1.2 equiv), DIPEA (3 equiv) and DMF (1.0 ml) is stirred at room temperature for 5 min. HATU (1.5 equiv) is added in 1 portion and stirred an additional 5 min. The crude reaction mixture is concentrated, filtered through a plug of silica eluted with acetone and evaporated to obtain crude 1,1-dimethylethyl 2-[4-({[2-[2-(2,3-difluorophenyl)ethyl]-4-oxo-1(4H)-quinazolinyl]acetyl} {[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]-2-methylpropanoate.
