الإجراء التجريبي

A mixture of 1,1-dimethylethyl 2-methyl-2-[4-({[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]propanoate (Int. B7) (150 mg, 1 equiv), [2-[2-(2,3-difluorophenyl)ethyl]-4-oxopyrido[2,3-d]pyrimidin-1(4H)-yl]acetic acid (Int. D1) (130 mg, 1.2 equiv), DIPEA (0.164 ml, 3 equiv) and DMF (1.0 ml) was stirred at room temperature for 5 min. HATU (180 mg, 1.5 equiv) was added in 1 portion and stirred an additional 5 min. The crude reaction mixture was 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-oxopyrido[2,3-d]pyrimidin-1(4H)-yl]acetyl}{[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]-2-methylpropanoate.
