Versuchsvorschrift

A flame dried 50 mL flask fitted with an addition funnel was charged with 0.872 g (500 mmol) of 5-nitroisoquinoline and 0.95 mL (5.1 mmol) of MTS. An acetonitrile solution of 1.40 g (5.09 mmol) of TASF was slowly added to the reaction mixture in 15 min at -78° C. The mixture was stirred for 22 h at that temperature. One mL of acetic acid in 5 mL of hexane was added, and reaction was warmed to room temperature. After 30 min, 40 mL of water was added. The solid which precipitated out was collected and analyzed. The product yield was 0.972 g (74%). The product material was analyzed by infrared spectroscopy, nuclear magnetic resonance spectroscopy, and mass spectrometry.
