Abstract

1,265,882. Benzofuran and benzothiophan derivatives. J. R. GEIGY A.G. 29 May, 1969 [30 May, 1968], No. 27281/69. Heading C2C. Novel compounds I: in which R is C 2-7 alkyl, X is O or S, Y 1 is H, CH 3 or CH 3 O, Y 2 is H or CH 3 and Z 1 and Z 2 are H, F, Cl, Br, CH 3 , C 2 H 5 , CH 3 0, or C 2 H 5 O and their salts with bases are prepared by reaction of a compound II: with a halide R-CO-Q, Q being halo, or an anhydride (R-CO) 2 O, followed where desired by salt formation. Intermediates isolated are the compounds II prepared by reduction of the corresponding 2,3- double-bonded compound with sodium amalgam; 6 - chloro - 2 - (2,3 - epoxypropyl) - phenol, prepared from 2-allyl-6-chlorophenol and peracetic acid; 2,3 - dihydro - 2 - hydroxymethyl- 7-chlorobenzofuran, prepared by heating the above epoxy compound; 2,3-dihydro-7-chlorobenzofuran-2-carboxylic acid prepared by oxidation of the 2-hydroxymethyl compound; a mixture of 4- and 6-chloro-2,3-dihydro-2-hydroxymethyl-benzofuran, prepared similarly to the above hydroxymethyl derivative; 2,3- dihydro - 6 - chloro - benzofuran - 2 - carboxylic acid, prepared by oxidation of the 2-hydroxymethyl compound; (X) 7, 8-dimethyl-coumarin, prepared from 2,3-dimethylphenol and malic acid; (Y) 6,7-dimethyl-benzofuran-2.carboxylic acid, prepared by reaction of the coumarin derivative with Br 2 and alcoholic potassium hydroxide; 7 - ethyl coumarin; 6 - ethyl - benzofuran - 2 - carboxylic acid; 7 - chloro - 8 - methylcoumarin and 6 - chloro - 7 - methyl - benzofuran- 2-carboxylic acid, the latter four compounds being prepared similarly to (X) and (Y) above; 6 - fluoro - benzofuran - 2 - carboxylic acid, prepared by reacting p -fluoro -salicylaldehyde with bromomalonic acid diethyl ester, followed by hydrolysis; (P) 2-thioxo-5-(2,4-dichlorobenzyl. idene)-4-thiazolidinone, prepared from rhodanine and 2,4-diohlorobenzaldehyde; 2,4-dichloro-α-mercapto-cinnamic acid, prepared from the above thiazolidinone by reaction with cone. HCl; (Q) 6-chloro-benzo[b]thiophene-2- carboxylic acid, prepared from the above cinnamic acid by cyclization; 2-thioxo.5.(2,6 dichlorobenzylidene)-4.thiazolidinone; 2,3 - dihydro - 4 - chloro - benzo[b]thiophene - 2 - carboxylic acid, the latter two being prepared similarly to (P) and (Q) above; 6-ethoxy-benzo[b]thiophene, prepared by reduction of the corresponding 3-one with NaBH 4 ; and 6-ethoxy-benzo[b] thiophene-2-carboxylic acid, prepared from the last-named intermediate by reaction with butyl lithium and solid CO 2 . Pharmaceutical compositions comprise a compound I together with a suitable carrier, are administered orally, rectally or parenterally, and have saluretic, antitussive and diuretic activity.
