37.4 mg (89.6 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(3-ethyloxetan-3-yl)propanoic acid (racemate), 15.9 mg (89.6 μmol) of 3-(4-aminophenyl)-1,2,4-oxadiazol-5(4H)-one, 12.7 mg (89.6 μmol) of Oxima and 14.0 μl (89.6 μmol) of DIC in 950 μl of dimethylformamide were reacted according to General Method 5. The crude product was purified by preparative HPLC [column: Chromatorex C18, 10 nm, 125 mm×30 mm, mobile phase: acetonitrile/0.05% formic acid gradient (0 to 3 min 10% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)] and then using Method 10. Yield: 2 mg (4% of theory)
