A process for preparing (1-oxo-2-cyclopentyl-2-methyl-6,7-dichloro-5-indanyloxy)acetic acid comprising reacting 5-cyclopentyl-5-methyl-2-cyclopentenone with a 4-carbon conjugated (open or cyclic) diene bearing vicinal chlorines adjacent to an ether group; aromatizing the resulting adduct to yield the desired indanone.
一种制备(1-氧代-2-环戊基-2-甲基-6,7-二氯-5-吲哚氧基)乙酸的方法,包括将5-环戊基-5-甲基-2-环戊烯酮与一种带有邻接于醚基的双键氯的4碳共轭(开环或环状)二烯反应;使得所得的加合物芳香化,从而得到所需的吲哚酮。
