摘要: A process for producing a thiophene derivative represented by a general formula (2) involves catalytically reducing a compound represnted by the general formula (1) with hydrogen in a solvent mixture of at least one of alcohol and water in the presence of a palladium catalyst soluble in organic solvents. A thiophene derivative is useful in preparing biotin (Vitamin H).
