Procedure

To a solution of 1-(4-(2-(2-aminopyridin-4-yl)ethoxy)naphthalen-1-yl)-3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)urea (7) (Intermediate D) (50 mg, 0.094 mmol) in pyridine (1.0 mL) was added trichloroacetylisocyanate (12 μl, 0.103 mmol). The mixture was stirred at RT until judged to be complete by LC-MS and solvent was evaporated under reduced pressure. The resulting residue was subjected to SCX capture and release and triturated from DCM (10 mL) to give 4-(2-(4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)ethyl)-3-(pyridin-2-yl)urea (Example 21) as an off white solid (25 mg, 44%): m/z 578 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.26 (9H, s), 2.38 (3H, s), 3.12 (2H, t), 4.35 (2H, t), 6.34 (1H, s), 6.94-6.99 (2H, m), 7.19 (1H, dd), 7.33-7.35 (2H, m), 7.41-7.50 (5H, m), 7.52-7.56 (1H, m), 7.60 (1H, d), 7.87 (1H, d), 8.09-8.13 (2H, m), 8.54 (1H, s), 8.75 (1H, s), 9.08 (1H, s).
