Procedure

A suspension of 1-(4-((2-aminopyrimidin-4-yl)methoxy)naphthalen-1-yl)-3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)urea (Intermediate H) (52 mg, 0.100 mmol) in DCM (1.0 mL) and DMF (100 μl) was treated with methoxyacetyl chloride (27 μl, 0.299 mmol) followed by DIPEA (52. μl, 0.299 mmol). After stirring overnight at RT, the volatiles were evaporated and the residue suspended in a mixture of MeOH (2.0 mL) and AcOH (2.0 mL). The suspension was subjected to SCX capture and release. Very little material eluted off hence the SCX from the cartridge was removed and extracted with MeOH (50 mL). After evaporation, an off white solid was obtained and this was triturated from MeOH (1.0 mL) and diethyl ether (5.0 mL) to give N-(4-((4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)methyl)pyrimidin-2-yl)-2-methoxy acetamide (Example 23) as a white solid (12 mg, 19% yield): m/z 594 (M+H)+ (ES+). 1H NMR (400 MHz, DMSO-d6) δ: 1.27 (9H, s), 2.40 (3H, s), 3.34 (3H, s), 4.24 (2H, s), 5.34 (2H, s), 6.35 (1H, s), 7.02 (1H, d), 7.35 (2H, d), 7.44 (3H, m), 7.60 (3H, m), 7.95 (1H, m), 8.36 (1H, m), 8.59 (1H, br s), 8.68 (1H, d), 8.80 (1H, br s), 10.44 (1H, br s).
