実験手順
N-Cyclopropyl-4-methyl-3-[4-oxo-6-[(2S)-pyrrolidin-2-ylmethoxy]quinazolin-3(4H)-yl]benzamide (0.15 g) and 38% aqueous formaldehyde (0.284 ml) were stirred in formic acid (3 ml) at 90° C. for 16 hours and then concentrated. The residue was partitioned between ethyl acetate and saturated aqueous NaHCO3 solution. The organic layer was washed with brine, dried (magnesium sulfate) and concentrated. Purification by column chromatography on a silica column eluting with 10% methanol/ethyl acetate followed by 10% methanol/ethyl acetate+1% aqueous ammonia solution to give the title compound (0.12 g) as a white foam solid; NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.70 (m, 2H), 1.70 (m, 3H), 1.99 (m, 1H), 2.14 (s, 3H), 2.22 (m, 1H), 2.39 (s, 3H), 2.62 (m, 1H), 2.85 (m, 1H), 2.96 (m, 1H), 3.99 (m, 1H), 4.09 (m, 1H), 7.52 (m, 2H), 7.60 (s, 1H), 7.73 (d, 1H), 7.83 (s, 1H), 7.91 (d, 1H), 8.19 (s, 1H), 8.42 (d, 1H); Mass Spectrum: M+H+ 433.
