Procedure

A solution of sodium hydroxide (0.173 g, 4.33 mmol) in water (5 mL) was added to a solution of silver nitrate (0.367 g, 2.16 mmol) in water (5 mL) to give a brown precipitate. 3-(5-(3-formyl-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl) pyridin-3-yl)-1,1-dimethylurea (CXXIII) (0.340 g, 0.86 mmol) was dissolved in 1,4-dioxane (10 mL) and added to the reaction which was stirred overnight at room temperature. The solution was diluted with water and then extracted with diethyl ether. The aqueous layer was separated and carefully brought to pH=3 with aqueous HCl. The aqueous layer was then extracted with 10% iPrOH/chloroform. The combined organic layers were then dried (Na2SO4), filtered and concentrated to give 5-(5-(3,3-dimethylureido)pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-3-carboxylic acid (CXXIV) as a brownish white solid (246 mg, 0.60 mmol, 70% yield). 1H NMR (DMSO-d6) δ ppm 13.26 (br. s, 1H), 8.87 (s, 1H), 8.63 (s, 1H), 8.41 (s, 1H), 8.34 (s, 1H), 8.03 (d, J=7.1 Hz, 1H), 7.86 (dd, J=7.2, 1.3 Hz, 1H), 6.06 (dd, J=8.0, 4.0 Hz, 1H), 3.92 (m, 1H), 3.80 (m, 1H), 2.98 (s, 6H), 2.42-2.39 (m, 1H), 2.03-2.02 (m, 2H), 1.79-1.77 (m, 1H) 1.61 (m, 2H); ESIMS found for C21H23N5O4 m/z 410.0 (M+H).
