Reaction Steps
A mixture 22.5 g of α-(o-methoxyphenylthiomethyl)-acrylic acid, 2.53 g of triethylamine and 200 ml of o-dichlorobenzene is heated for 12 hours at 195°. After dilution with ether the products are extracted with sodium bicarbonate solution. Acidification of the basic extracts affords 8-methoxy-3,4-dihydro-2H-[1]-benzothiopyran-3-carboxylic acid, m.p. 138°-144°.
