Paragraph 0018; 0023; 0025, (2018/01/19)
The invention relates to a thienopyridine ester compound and a preparation method thereof. The thienopyridine ester compound is 6-chloro-2-thiazole [4, 5-b] picolinic acid methyl ester. The preparation method comprises the following steps: (1) obtaining benzoyl protected thiourea-containing derivative compound 2 by using a compound 13,5-dichloro-2-aminopyridine as a starting material in the presence of benzoyl chloride and ammonium thiocyanate; (2) hydrolyzing the compound 2 so as to obtain a thiourea derivative compound 3; (3) carrying out ring-closing reaction on the compound 3 under the action of sodium hydride so as to generate a compound 4; (4) deaminizing the compound 4 by using isoamyl nitrite so as to obtain a target compound 5; and (5) carrying out catalytic carbonyl insertion on the compound 5 by using carbon monoxide so as to obtain a target compound 6. The preparation method is a 6-chloro-2-thiazole [4, 5-b] picolinic acid methyl ester preparation method which has the advantages that raw materials are low in cost, and the synthetic method is simple. The product prepared by the method has a wide application prospect in the preparation of anti-inflammatory medicines.
