1-(2-Methoxyphenyl)piperazine → HCID 66881744, compound

Participants

Reaction Steps

To a stirred suspension of [4-(3-bromopropyloxy)-5-methoxy-2-nitrophenyl][4-(2-methoxyphenyl)piperazino]methanone (9) (500 mg, 1.65 mmol), 1-(2-methoxyphenyl)piperazine (316 mg 15.6 mmol) and K2CO3 (816 mg 26.6 mmol) in acetone (30 mL) and the stirring was continued for 16 h. The acetone was evaporated in vacuum and the aqueous layer was washed with ethyl acetate and extracted with ethyl acetate and washed with brine, dried over Na2SO4 and evaporated in vacuum to afford the crude product to (5-methoxy-4-3-[4-(2-methoxyphenyl)-piperazino]propoxy-2-nitrophenyl)[4-(2-methoxyphenyl)piperazino]methanone (10) in 93% yield (670 mg, 85% yield). 1H NMR (CDCl3): δ 1.60-2.15 (m, 2H), 2.98-3.12 (t, 2H, J=7.31 Hz), 3.18-3.36 (m, 8H), 3.38-3.60 (m, 10H), 3.85 (m, 3H), 3.95 (s, 3H), 4.00-4.15 (m, 3H) 6.85-7.00 (m, 8H), 7.20-7.40 (m, 1H), 7.70-7.80 (d, 1H, J=6.81 Hz); FABMS: 619 (M+H)+.
