Preparation of the bisphosphate salt of cyclopropane-l,l-dicarboxylic acid {3-fluoro-4- [6-methoxy-7-(3-morpholin-4-yl-propoxy)-quinolin-4-ylamino]phenyl}-amide (4-fluoro- phenyl)-amide

[00200] Cyclopropane- 1,1-dicarboxy lie acid {3-fluoro-4-[6-methoxy-7-(3-morpholin-4-yl- propoxy)-quinolin-4-ylamino]phenyl}-amide-(4 fluoro phenyl)-amide from the previous step was dissolved in acetone and water. Phosphoric acid (85%, 372.48 g) was added at a rate such that the batch temperature did not exceed 30 °C. The batch was maintained at approximately 15- 30 °C with stirring for 1 hour during which time the product precipitated. The solids were collected by filtration, washed with acetone and dried at approximately 60 °C under vacuum to afford the title compound (1.533 kg). The title compound has a c-Met IC50 value of less than 50 nM. The bisphosphate salt is not shown in scheme 1. Ή NMR (400

MHz, DMSO-d6): (diphosphate) δ 10.41 (s, 1H), 10.02 (s, 1H), 8.48 (d, 1 H), 7.93 (dd, 1H), 7.65 (m, 2H), 7.53 (d, 2H), 7.42 (m, 2H), 7.17 (m, 2H), 6.48 (d, 1H), 5.6 (br s, 6H), 4.24 (t, 2H), 3.95 (s, 3H), 3.69 (bs, 4H), 2.73 (bs, 6H), 2.09 (t, 2H), 1.48 (d, 4H).
