Participants

Reaction Steps

Using the same procedure as in Example 26, methyl (2R)-2-[(4-{[1-(1,3-thiazol-4-ylmethyl)-1H-indazol-5-yl]amino}quinazolin-5-yl)oxy]propanoate (200 mg, 0.43 mmol) was reacted with 2-(methylamino)ethanol (0.35 ml, 4.3 mmol) to give the title compound as a solid (160 mg, 73%), except that the mixture was heated at 45° C. for 20 hours and purified by chromatography on silica gel (eluant: 3% methanol in DCM). NMR Spectrum (2 rotamers) 1.60 (m, 3H), 3.18 and 2.93 (s, 3H), 3.65-3.40 (m, 4H), 5.00 and 4.73 (t, 1H), 5.79 (s, 2H), 5.90 and 5.81 (q, 1H), 7.35-7.30 (m, 2H), 7.51 (s, 1H), 7.85-7.70 (m, 3H), 8.11 (s, 1H), 8.51 (m, 2H), 9.04 (s, 1H), 11.09 (br s, 1H); Mass spectrum MH+ 504.
