Stage #1: With dmap In tetrahydrofuran at 20℃; for 0.5 h;
Stage #2: for 2 h;
In a 100 mL round-bottom flask was placed 1H-INDOLE-5-CARBONITRILE (2.0 g, 14.07 MMOL) in 20 mL of anhydrous THF. To this solution was added DMAP (0.86 g, 7.03 MMOL) and the mixture was allowed to stir for 0.5 h at rt. At this point, BOC20 (3.07 g, 14.07 MMOL) was added and the reaction stirred for an additional 2 h. The reaction was then quenched with water and extracted twice with ethyl ether. The combined organic layers were washed successively with 1 N HCI, water, and brine, then dried over MGS04 and concentrated to provide 3.26 g (96percent) of the desired product as a white SOLID.APOS;H- NMR (DMSO-d6) 8 8.20-8. 14 (m, 2H), 7.83 (d, 1H), 7.70 (d, 1H), 6.80 (d, 1H), 1.63 (s, 9H).
