The present invention provides, in part, novel small molecule inhibitors of PHD, having a structure according to Formula (A), and sub-formulas thereof: or a pharmaceutically acceptable salt thereof. The compounds provided herein can be useful for treatment of diseases including heart ( e.g. ischemic heart disease, congestive heart failure, and valvular heart disease), lung (e.g., acute lung injury, pulmonary hypertension, pulmonary fibrosis, and chronic obstructive pulmonary disease), liver (e.g. acute liver failure and liver fibrosis and cirrhosis), and kidney (e.g. acute kidney injury and chronic kidney disease) disease.
Synthetic method for 1-(ethoxycarbonyl)imidazo[1,5]pyridine-6-carboxylic acid
-
Paragraph 0007, (2019/10/01)
The invention relates to a synthetic method for 1-(ethoxycarbonyl)imidazo[1,5]pyridine-6-carboxylic acid, and mainly solves the technical problem that a current method is not suitable for industrial synthesis. The method comprises the following three steps: step 1, firstly performing a reaction on a compound 1 and di-tert-butyl dicarbonate in solvent tetrahydrofuran under the action of 4-dimethylaminopyridine to obtain a compound 2; step2, performing a reaction on the compound 2 and ethyl cyanoacetate in solvent N,N-dimethylformamide under the action of cesium carbonate to obtain a compound 3;and step 3, performing a reaction on the compound 3 under the action of hydrochloric acid-ethyl acetate to obtain the 1-(ethoxycarbonyl)imidazo[1,5]pyridine-6-carboxylic acid. The reaction formula isshown in the description.
