b) Benzo[b]thiophene-6-carboxaldehyde A mixture of 6-bromobenzo[b]thiophene [9.6 g; prepared according to Nippon Kagaku Zasshi, 88 , 758 (1967): Chem. Abstr., 69 , 59018q (1968)], magnesium (1.64 g), and 1,2-dibromoethane (4.23 g) in anhydrous diethyl ether (90 ml) was stirred and gently heated for 3 hr. N-formylpiperidine (5.09 g) in anhydrous diethyl ether (15 ml) was added to the cooled mixture which was subsequently allowed to stand for 12 hr. the mixture was poured into a dilute hydrochloric acid solution. the dried (MgSO4) ether extract was evaporated and the residue was purified by column chromatography over silica gel with chloroform/hexane (1:8 v/v) elution to give benzo[b]thiophene-6-carboxaldehyde as yellow oil. Pmr spectrum (CDCl3; delta in ppm): 7.36 (1H,d); 7.68 (1H,d); 7.84 (2H,s); 8.16 (1H,s); 10.04 (1H,s).
