Procedure
Benzyl 2-[5-(benzoyloxy)-4-(methoxycarbonyl)-1-methyl-6-oxo-1,6-dihydropyrimidin-2-yl]-1,2,3,4-tetrahydroquinoline-1-carboxylate (prepared from tetrahydroquinoline-2-carboxylic acid (Robl et al, Tetrahedron Letters 1995, 36: 1593) by protection of the nitrogen and following procedures similar to those set forth in Examples 1 or 2 in combination with a deprotection step) was dissolved in EtOAc and hydrogenated at atmospheric pressure on 10% Pd/C at room temperature overnight. The title product was obtained as the residue after filtration and evaporation of the organic solvent.
