Methods 4-Hydroxybenzonitrile (2) as the starting material was transformed to 4-hydroxy-thiobenzamide (3) via thioformylation. And ethyl 2-(4-hydroxyphenyl)-4-methylthiazole-5-carboxylate (4), which was synthesized via cyclization from 3, was treated with hexamethylenetetramine to generate the intermediate ethyl 2-(3-formyl-4-hydroxyphenyl)-4-methylthiazole-5-carboxylate (5). The target compound febuxostat (1) was obtained from 5 by etherification, cyanidation, hydrolysis.

HCo 〓-catalyzed hydroformylation and isomerization of allene and propyne Allene hydroformylation favors the linear anti-Markovnikov product in high regioselectivity both kinetically and thermodynamically. The origin of this regioselectivity comes from the enhanced stability of the η〓-allylic intermediate (η〓-CH〓CHCH〓 Co 〓.
HCo〓催化的丙二烯和丙炔氢甲酰化反应及异构化反应 HCo〓催化丙二烯氢甲酰化反应的区域选择性主要由不可逆的丙二烯插入步骤决定，动力学和热力学因素都有利于形成anti-Markovnikov中间物种(η〓-CH〓CHCH〓)Co〓，形成Markovnikov中间物种Co〓是不具有竞争性的。
