Procedure
2-Methylindole-2-sulfonyl chloride was prepared by the method of Example 34 with 1-methylindole (7.8 mmols, 1.0 ml), t-BuLi (1.7 m, 9.4 mmols, 5.5 ml), sulfur dioxide, NCS (8.6 mmols, 1.2 g) and THF (15 ml). Flash chromatography (2% ethyl acetate/hexanes) provided 0.66 g (36%) of a yellow solid.
