Reaction Steps

110 mg (283 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-4,4-dimethylpentanoic acid (racemate), 65.6 mg (339 μmol) of tert-butyl 4-aminobenzoate, 129 mg (339 μmol) of HATU and 148 μl (849 μmol) of N,N-diisopropylethylamine in 9 ml of dimethylformamide were reacted according to General Method 5A. The solvent was removed and the residue was purified by preparative HPLC [column: Chromatorex C18, 10 μm, 125×30 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)]. Yield: 100 mg (62% of theory)
