Versuchsvorschrift
A mixture of 5-nitroindoline (I, 12.012 g) in pyridine (100 ml) and acetic anhydride (50 ml) is stirred for 17 hr under argon. The mixture is then concentrated under reduced pressure to give the title compound, mp 175°-177°; NMR (CDCl3, 300 MHz) 8.28, 8.10, 8.01, 4.23, 3.31 and 2.28 δ; CMR (CDCl3, 75.47 MHz) 23.95, 27.01, 49.11, 115.73, 119.93, 124.27, 132.4, 143.4 and 169.8 δ; IR (CHCl3) 1680, 1600, 1480, 1470, 1390, 1340 and 1320 cm-1.
