Reaction Steps

A 3 dram vial was charged with bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (0.488 g, 1.05 mmol), 4-fluoro-3-(2-(4-methylthiazol-2-ylamino)pyridin-4-yloxy)benzoic acid hydrochloride (Example 107; 0.200 g, 0.524 mmol), N-(2-aminoethyl)pyrrolidine (0.179 g, 1.57 mmol) and DMF (3 mL). The reaction was stirred for 1 hour at ambient temperature. Water was added and the reaction was extracted with ethyl acetate, dried over sodium sulfate, filtered and concentrated. The residue was purified by flash column chromatography. 2M HCl in ether was added to the isolated material and the collected solids were dried over high vacuum to give the title compound (0.078 g, 28.9% yield) as a white solid. 1H NMR (d6-DMSO) δ 11.21 (bs, 1H), 9.75 (bs, 1H), 8.86 (t, 1H), 8.23 (m, 1H), 7.92 (m, 2H), 7.64 (dd, 1H), 6.62 (m, 2H), 6.58 (d, 1H), 3.60 (m, 4H), 3.32 (quart, 2H), 3.03 (m, 2H), 2.21 (d, 3H), 2.00 (d, 2H), 1.85 (m, 2H).
