実験手順

A mixture of [2-[2-(2,3-difluorophenyl)ethyl]-4-oxopyrido[2,3-d]pyrimidin-1(4H)-yl]acetic acid (Int. D1) (20.7 g, 1.3 equiv), methyl 2-methyl-2-[4-({[4′-(trifluoromethyl)-4-biphenylyl]methyl}amino)-1-piperidinyl]propanoate (Int. B1) (20.0 g, 1.3 equiv), DIPEA (24.0 ml, 3 equiv) and DMF (184 ml) was mechanically stirred, then HATU (27.1 g, 1.5 equiv) was added in one portion and stirring continued for 2 h. The reaction mixture was partioned between diethyl ether/THF (1:1) and sodium carbonate (1M, excess). The organic layer was washed with water and brine, dried and evaporated. Chromatography was run sequentially on three silica columns (firstly 3:1 EtOAc/hexanes; secondly 2% MeOH in DCM; thirdly 1:1 EtOAc/hexanes to 100% EtOAc). Product fractions were evaporated to obtain the desired product as an amorphous pink solid (27.5 g).
