実験手順
416 mg (1.00 mmol) of tert-butyl [5-chloro-4-(5-chloro-2-cyanophenyl)-2-oxopyridin-1(2H)-yl]acetate in the presence of 0.95 ml (0.95 mmol, 1.2 eq.) of bis(trimethylsilyl)lithium amide (1M in THF) and 326 mg (1.58 mmol, 2.0 eq.) of isobutyl trifluoromethanesulphonate were reacted according to General Method 7B. Yield: 139 mg (purity 85%, 34% of theory)
