Reaction Steps

Ethyl 2-[1-[4-(2-naphthamido)benzyl]-6-fluoro-1H-indazol-3-yl]acetate (205 mg, 0.426 mmol) was dissolved in tetrahydrofuran (15 mL), and in an ice bath 10 mL aqueous solution dissolving lithium hydroxide monohydrate (54 mg, 1.29 mmol) was added. It was reacted at room temperature for 3 h, and the reaction was monitored to be complete by TLC. Water was added into the system, adjusted to pH≈3-4 with diluted hydrochloric acid. A solid precipitated, which was filtered and dried to obtain a white solid 165 mg, at a yield of 85.4%.
