Procedure
To a solution of N-(4-((4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)methyl)pyridin-2-yl)-2-chloroacetamide (Intermediate B) (50 mg, 0.08 mmol) in DCM (1.0 mL), DMF (0.1 mL) and DIPEA (17 μl, 0.10 mmol) was added 2-methoxyethylamine (7.0 μl, 0.08 mmol). The reaction mixture was heated to 40° C. and stirred for 12 hr. The crude reaction mixture was purified by column chromatography (12 g, 0-10% MeOH in DCM, gradient elution). Product fractions were concentrated in vacuo and the residue triturated with a mixture of diethyl ether, DCM and iso-hexane (2:1:2, 5.0 mL) to afford N-(4-((4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)methyl)pyridin-2-yl)-2-(2-methoxyethylamino)acetamide (Example 11) as an off-white solid (6 mg, 11%): m/z 637 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.39 (3H, s), 2.71 (2H, t), 3.24 (3H, s), 3.33 (2H, m (obscured by DHO)), 3.40 (2H, t), 5.38 (2H, s), 6.35 (1H, s), 7.01 (1H, d), 7.27 (1H, d), 7.36 (2H, d), 7.43 (2H, d), 7.64-7.57 (3H, m), 7.92 (1H, m), 8.36-8.30 (3H, m), 8.59 (1H, s), 8.79 (1H, s).
