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 (17.5 μl, 0.10 mmol) was added N-(4-methoxybenzyl)-N-methylamine (15.5 μl, 0.09 mmol) The reaction mixture was stirred at 55° C. 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-((4-methoxybenzyl)(methyl)amino)acetamide (Example 14) as a white solid (7 mg, 11%): m/z 713 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.25 (3H, s), 2.39 (3H, s), 3.22 (2H, s), 3.59 (2H, s), 3.72 (3H, s), 5.38 (2H, s), 6.35 (1H, s), 6.90 (2H, m), 7.01 (1H, m), 7.27 (3H, m), 7.35 (2H, m), 7.43 (2H, m), 7.64-7.55 (3H, m), 7.94 (1H, m), 8.37-8.28 (3H, m), 8.58 (1H, s), 8.79 (1H, s), 9.97 (1H, s).
