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 (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 (173 mg, 79%), except that the mixture was heated at 45° C. for 24 hours and purified on an HPLC column (C18, 5 microns, 19 mm diameter, 100 mm length) of a preparative HPLC-MS system eluting with a mixture of water and acetonitrile containing 2 g/l of ammonium carbonate (gradient). NMR Spectrum (2 rotamers) 1.60-1.63 (m, 3H), 3.18 and 2.93 (s, 3H), 3.41-3.65 (m, 4H), 5.01 and 4.75 (br s, 1H), 5.81 and 5.91 (q, 1H), 6.04 (s, 2H), 7.30-7.36 (m, 2H), 7.66 (s, 1H), 7.71-7.78 (m, 3H), 8.84-8.90 (m, 1H), 8.20 (s, 1H), 8.52 (s, 1H), 8.55 and 8.58 (s, 1H), 11.12 (br s, 1H); Mass spectrum MH+ 504.
