Procedure

To a solution of 1-(4-((2-aminopyridin-4-yl)methoxy)naphthalen-1-yl)-3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)urea (Intermediate A) (70 mg, 0.13 mmol) in anhydrous pyridine (1.5 mL) was added methyl isocyanate (14 μL, 0.24 mmol) and the mixture allowed to stir at RT for 72 hr. Pyridine was removed under vacuum and the residue triturated with DCM (3.0 mL). Filtration afforded an off-white powder, methyl 4-((4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)methyl)pyridin-2-ylurea (Example 2) (36 mg, 45%): m/z 578 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.39 (3H, s), 2.74 (3H, d), 5.30 (2H, s), 6.36 (1H, s), 6.99 (1H, d), 7.05 (d, 1H), 7.35, (2H, d), 7.44 (2H, d), 7.54-7.64 (4H, m), 7.93 (1H, d), 8.19 (1H, d), 8.23 (1H, brs), 8.35 (1H, d), 8.58 (1H, s), 8.79 (1H, s), 9.36 (1H, s).
