実験手順

2-chloro-4-[(5-fluoroquinazolin-4-yl)amino]phenol (2 g) was added to a stirred solution of (2R)-1-[allyl(methyl)amino]propan-2-ol (2.24 g, prepared as described in Example 2-3) in DMA (100 ml) and sodium hydride (60% dispersion in oil, 692 mg), and the mixture heated to 110° C. for 16 hours. The mixture was concentrated in vacuo then a saturated solution of sodium bicarbonate (200 ml) was added and extracted with DCM (300 ml). The extract washed with brine, dried and concentrated in vacuo and the residue purified by chromatography using DCM—10% methanol/2N ammonia as eluent to give 4-[(5-{(1R)-2-[allyl(methyl)amino]-1-methylethoxy}quinazolin-4-yl)amino]-2-chlorophenol as a yellow solid (1.88 g, 68%); NMR spectrum (DMSO-d6) 1.43 (d, 3H), 2.17 (s, 3H), 2.54 (dd, 1H), 2.97 (m, 3H), 4.94 (m, 1H), 5.00 (dd, 1H), 5.10 (dd, 1H), 5.63 (m, 1H), 6.98 (d, 1H), 7.18 (d, 1H), 7.29 (d, 1H), 7.42 (dd, 1H), 7.69 (t, 1H), 7.84 (d, 1H), 8.44 (s, 1H), 10.01 (bs, 1H), 10.26 (s, 1H); Mass spectrum MH+ 399.
