Participants

Reaction Steps

A solution of yield of t-butyl 6-(3-t-butyl-5-(3-(2,3-dichlorophenyl)ureido)-1H-pyrazol-1-yl)-1H-indazole-1-carboxylate (0.13 g, 0.239 mmol, 1.00 eq) in satd. HCl/EtOH (5.00 ml) and stirred at 65° C. for 2 h until the reaction was clear and homogeneous. It was cooled to RT and evaporated. The syrupy residue was dissolved in MeCN/H2O, frozen and lyophilized to yield 1-(3-t-butyl-1-(1H-indazol-6-yl)-1H-pyrazol-5-yl)-3-(2,3-dichlorophenyl)urea (97.1 mg, 85% yield) as the HCl salt. 1H NMR (DMSO-d6): δ 9.32 (s, 1H), 8.81 (s, 1H), 8.17-8.16 (m, 1H), 8.13-8.12 (m, 1H), 8.10-8.07 (m, 1H), 7.92-7.82 (m, 1H), 7.65-7.59 (m, 1H), 7.24-7.25 (m, 2H), 6.44 (s, 1H), 1.30 (s, 9H); MS (ESI) m/z: 443.0 (M+H+), 445.0 (M+2+H+).
