Reaction Steps

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, 0.1 mmol) was added dimethylamine (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 silica, 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-(dimethylamino) acetamide (Example 12) as an orange solid (18 mg, 35%): m/z 607 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.31 (6H, s), 2.39 (3H, s), 3.14 (2H, s), 5.39 (2H, s), 6.35 (1H, s), 7.01 (1H, d), 7.29 (1H, d), 7.35 (2H, d), 7.44 (2H, d), 7.65-7.55 (3H, m), 7.94 (1H, m), 8.38-8.28 (3H, m), 8.59 (1H, s), 8.79 (1H, s), 9.93 (1H, s).
