Participants

Reaction Steps

Using the same procedure as in Example 26, methyl (2R)-2-[(4-{[1-(1,3-thiazol-2-ylmethyl)-1H-indazol-5-yl]amino}quinazolin-5-yl)oxy]propanoate (250 mg, 0.54 mmol) was reacted with pyrrolidine (0.45 ml, 5.4 mmol) to give the title compound (160 mg, 59%) as a solid, except that the mixture was heated at 55° C. for 20 hours and purified by chromatography on silica gel (eluant: 1-5% methanol in DCM); NMR Spectrum 1.61 (d, 3H), 1.82 (m, 2H), 1.94 (m, 2H), 3.47-3.30 (m, 3H), 3.77 (m, 1H), 5.63 (q, 1H), 6.04 (s, 2H), 7.27 (d, 1H), 7.35 (d, 1H), 7.65 (d, 1H), 7.74 (m, 3H), 7.88 (dd, 1H), 8.20 (s, 1H), 8.52 (s, 1H), 8.56 (s, 1H), 11.09 (br s, 1H); Mass spectrum 500.
