実験手順

500 mg (1.32 mmol) of tert-butyl [5-chloro-4-(5-chloro-2-cyanophenyl)-2-oxopyridin-1(2H)-yl]acetate in the presence of 1.58 ml (1.58 mmol, 1.2 eq.) of bis(trimethylsilyl)lithium amide (1M in THF) were reacted with 556 mg (purity 74%, 1.98 mmol, 1.5 eq.) of 2-methoxyethyl trifluoromethanesulphonate according to General Method 7B. Yield: 455 mg (purity 80%, 63% of theory)
