| titleOfInvention | Method for producing 5-hydroxybenzo [b] thiophene-3-carboxylic acid derivative |
| abstract | PROBLEM TO BE SOLVED: To provide a novel method for producing a benzothiophenic acid derivative (I) useful for producing a 5-hydroxybenzo [b] -thiophene-3-carboxylic acid derivative which is a specific PGD 2 antagonist I will provide a. SOLUTION: Hydroxy-protected 5-hydroxybenzo [b] thiophene (VII) is reacted with acetyl halide under the conditions of Friedel-Crafts reaction to oxidize the acetyl group of the obtained compound (VIII). Formula (I) characterized by deprotection: (Wherein R represents hydrogen or a hydroxy protecting group) or a reactive derivative thereof. |
