Procedure

A mixture of 1-methylethyl 2-methyl-2-[4-({[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]propanoate (Int. B3) (420 mg, 1 equiv), [2-[2-(2,3-difluorophenyl)ethyl]-4-oxopyrido[2,3-d]pyrimidin-1(4H)-yl]acetic acid (Int. D1) (300 mg, 1 equiv), HATU (396 mg, 1.2 equiv), DIPEA (0.22 ml, 1.5 equiv) and DMF (3.0 ml) was stirred at room temperature for 30 min. The crude reaction mixture was applied directly to reverse-phase HPLC (Preparative Method A) to obtain 1-methylethyl 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 (171 mg).
