500 mg (1.33 mmol) of tert-butyl [4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]acetate, 701 mg (2.58 mmol) of [1-(trifluoromethyl)cyclopropyl]methyl trifluoromethanesulphonate and 1.73 ml (1.73 mmol) of bis(trimethylsilyl)lithium amide (1M in THF) in 13 ml of THF were reacted according to General Method 7B. The crude product was purified by column chromatography (ethyl acetate/cyclohexane gradient, 40 g silica cartridge, flow rate 40 ml/min), giving the title compound. Yield: 295 mg (45% of theory)
