Versuchsvorschrift

A mixture of 4-chloro-2-nitrobenzonitrile (7.828 g, 42.9 mmol) and morpholine (4.49 mL, 51.5 mmol) in DMSO (20.00 mL) was stirred at rt for 1 h, after which time LC-MS indicated a small amount of desired product formed. The reaction was heated to 100° C. After 24 h the reaction was equilibrated to rt and poured into 50 mL ea 1N aq. hydrochloric acid and EtOAc. The resulting orange precipitate was collected by filtration, rinsing with EtOAc, then dried under vacuum. Mass Spectrum (ESI) m/e=234.1 (M+1).
