Participants

Reaction Steps

A mixture of 4.2 g of 3,4-dichloro-6,7,8,9-tetrahydro-2-methoxy dibenzothiophene and 40 g of pyridine hydrochloride is stirred at 190°-195° under nitrogen for 2 hours. The cooled mixture is triturated with water and the solid product is collected. Recrystallization from ether-pentane after decolorization with charcoal gave 3.6 g of 3,4-dichloro-6,7,8,9-tetrahydro-2-hydroxydibenzothiophene as off-white crystals, mp 103°-105°.
