Procedure

K2CO3 (5.08 g, 36.726 mmol) was added to a slurry of 6-nitroindole (1.985 g, 12.242 mmol), 4-(2-chloroethyl)morpholine hydrochloride (2.278 g, 12.242 mmol), and CH3CN (100 ml). The mix was heated at reflux for 18 h, then cooled to RT, filtered, and concentrated in vacuo. The crude was eluted through a silica gel column with a gradient of 3:97 to 5:95 and finally 8:92 MeOH:CH2Cl2, to yield upon drying 1-(2-morpholin-4-yl-ethyl)-6-nitro-1H-indole which was hydrogenated at regular condition described early to yield the title compound.
