2-Methyl- and 2-ethyl-3-(α-aryl)hydroxymethylbenzothiophene (6a)-(6d) were heated at 400 deg C for 5 min to yield the corresponding benzonaphthothiophene derivatives (9a)-(9d), respectively.In a similar fashion, the alcohol (8a) gave 5-methylbenzonaphthothiophene (9e) and 5,10-dimethyl derivative (3). 8-Methoxy-5-methyl- (9f) and 5-phenyl derivative (9g) were obtained from the corresponding alcohols (8b) and (8c), respectively.
