Versuchsvorschrift

N-{5-[(Cyclopropylamino)carbonyl]-2-methylphenyl}-2-nitro-5-[(2S)-pyrrolidin-2-ylmethoxy]benzamide hydrochloride salt (2.05 g) and 10% palladium on carbon (0.2 g) were stirred in ethanol (40 ml) and methanol (20 ml) under an atmosphere of hydrogen gas for 19 hours at room temperature. The catalyst was removed by filtration through diatomaceous earth (Celite®) and the filtrate was concentrated. The residue was dissolved in ethanol (40 ml) and stirred with triethylorthoformate (2.16 ml) and glacial acetic acid (0.124 ml) at 80° C. for 3 hours and then concentrated. The residue was diluted with ethyl acetate and washed with saturated aqueous NaHCO3 solution, brine, dried (magnesium sulfate) and concentrated. Purification by column chromatography on a silica column eluting with 20% methanol/ethyl acetate followed by 20% methanol/ethyl acetate+1% aqueous ammonia solution to give N-cyclopropyl-4-methyl-3-[4-oxo-6-[(2S)-pyrrolidin-2-ylmethoxy]quinazolin-3(4H)-yl]benzamide (AZ12299441) (0.837 g) as a cream coloured foam solid; NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.70 (m, 2H), 1.49 (m, 1H), 1.61-1.76 (m, 2H), 1.85 (m, 1H), 2.15 (s, 3H), 2.85 (m, 3H), 3.42 (m, 1H), 3.95 (d, 2H), 7.52 (m, 2H), 7.58 (s, 1H), 7.73 (d, 1H), 7.84 (s, 1H), 7.91 (d, 1H), 8.19 (s, 1H), 8.42 (d, 1H); Mass Spectrum: M+H+ 419.
