Procedure
500 mg (1.26 mmol) of tert-butyl [4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]acetate, 445 mg (2.27 mmol) of 2-fluoroethyl trifluoromethanesulphonate and 1.39 ml (1.39 mmol) of bis(trimethylsilyl)lithium amide (1M in THF) in 10 ml of THF were reacted according to General Method 7B. Purification by column chromatography (120 g silica cartridge, flow rate: 80 ml/min, cyclohexane/ethyl acetate gradient) gave the title compound. Yield: 360 mg (67% of theory)
