Procedure
2-i-Propylbenzo[b]thiophene was prepared by the method of Example 40A with benzo[b]thiophene (7.5 mmoles, 1.0 g), t-BuLi (1.7M, 11.2 mmoles, 6.6 ml), 2-iodopropane (11.2 mmoles, 1.12 ml) and THF (20 ml) with stirring at ambient temperature for 24 hrs. It was isolated as a yellow oil (1.11 g; 85% yield).
