4-BroMo-1H-indazol-5-carboxylic acid tert-butyl ester Chemical Properties, Uses, Production

Uses

tert-Butyl 4-Bromo-1H-indazole-5-carboxylate could be prepared as inhibitors of MNK1 and MNK2, which are useful in treating MNK-mediated diseases.

Synthesis

Benzoic acid, 2-broMo-4-fluoro-3-forMyl-, 1,1-diMethylethyl ester

1203662-35-4

4-BroMo-1H-indazol-5-carboxylic acid tert-butyl ester

1203662-37-6

Step 3: Synthesis of tert-butyl 4-bromo-1H-indazole-5-carboxylate [0245] Tert-butyl 2-bromo-4-fluoro-3-formylbenzoate (4.25 g, 14 mmol) was dissolved in DME (25 mL), hydrazine hydrate (15 mL) was added, and the reaction was heated for 1 hr at 90 °C. After completion of the reaction, it was cooled to room temperature and the reaction mixture was partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate, the organic phases were combined, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give tert-butyl 4-bromo-1H-indazole-5-carboxylate as a brown solid (4.1 g, 100% yield). LCMS (Method B): retention time (Rx) = 3.63 min, [M + CH3CN + H]+ = 338/340, [M-H] = 295/297.
