Procedure

25 mg (44 μmol) of allyl 4-({2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(3-methyloxetan-3-yl)propanoyl}amino)benzoate (racemate) and 48.2 μl (445 μmol) of N-methylaniline were initially charged in 1 ml of tetrahydrofuran, and the resulting solution was degassed. 5 mg (4 μmol) of tetrakis(triphenylphosphine)palladium(0) were then added, and the mixture was stirred at room temperature for another 30 min. The reaction solution was purified directly by preparative HPLC (neutral) and the title compound was obtained after final preparative thin-layer chromatography (ethyl acetate/cyclohexane=1:1). Yield: 10.1 mg (purity 92%, 42% of theory)
