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 (0.2 mL) and DIPEA (17 μl, 0.10 mmol) was added methylamine (2.0M solution in THF) (41 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 contaminated with an impurity; the crude material was re-purified by column chromatography (12 g, 0-10% MeOH in DCM, gradient elution) 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-(methylamino) acetamide (Example 13) as a light brown solid (6 mg, 12%): m/z 593 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.32 (3H, s), 2.39 (3H, s), 3.28 (2H, s), 5.39 (2H, s), 6.35 (1H, s), 7.01 (1H, d), 7.27 (1H, d), 7.35 (2H, d), 7.44 (2H, d), 7.63-7.55 (3H, m), 7.93 (1H, m), 8.37-8.30 (3H, m), 8.59 (1H, s), 8.80 (1H, s).
