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 to 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 the desired intermediate which was hydrogenated under conditions previously described.
