The reaction mixture of (S)-methyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (20 mg, 0.039 mmol), 1-methyl-1H-indazole-6-boronic acid (10.3 mg, 0.058 mmol), 2N K2CO3 (100 μL, 0.19 mmol), Pd(PPh3)4 (4.3 mg, 0.004 mmol) in dioxane (1.5 mL) in sealed tube was heated at 110° C. for 2 h. After the starting material consumed, the reaction was cooled down, to the mixture was added MeOH, excess NaOH, the reaction mixture was heated at 45° C. overnight. Then the reaction mixture was neutralized by acetic acid, concentrated down, then treated by MeOH, and purified by reverse phase HPLC, eluting by 0-100% acetonitrile in H2O with 0.1% TFA to give the product. LCMS-ESI+: calc'd for C33H29ClN4O3S: 597.2 (M+H+). Found: 597.2 (M+H+). 1H NMR (400 MHz, CD3OD): δ 8.78 (d, J=2.6 Hz, 1H), 8.60 (s, 1H), 8.26 (s, 1H), 8.06 (s, 1H), 8.03-7.82 (m, 4H), 7.71-7.69 (m, 1H), 7.61-7.60 (m, 3H), 5.28 (s, 1H), 4.16 (s, 3H), 2.64 (s, 3H), 0.98 (s, 9H).
