Versuchsvorschrift

To a stirred solution of 1-iodo-4-methoxy-2-nitrobenzene (0.2 g, 0.0007 mol) in toluene (6.0 mL) was added cyclopropylamine (0.068 ml, 0.0008 mol) potassium tert-butoxide (0.094 g, 0.0098 mol) and Ruphos (0.049 g, 0.00010 mol) at room temperature and purged with argon for 15 min. Then Pd2(dba)3 (0.064 g, 0.00007 mol) was added and resulting mixture was heated to 100° C. in CEM microwave for 30 min. After the reaction was complete the reaction mixture was filtered through CELITE® bed and the bed was thoroughly washed with ethyl acetate. The filtrate was washed with water brine dried over Na2SO4 and concentrated under reduced pressure to afford the crude compound, which was purified by column chromatography to obtain title compound cyclopropyl-(4-methoxy-2-nitro-phenyl)-amine (yellow solid). C10H12N2O3; 1H NMR (400 MHz, CDCl3), δ: 7.98 (s, 1H), 7.60 (d, J=2.8 Hz, 1H), 7.30 (s, 1H), 7.19-7.16 (m, 1H), 4.12 (q, J=6.8, 1H), 3.80 (s, 1H), 0.89 (dd, J1=12.0 Hz, J2=6.0 Hz, 2H), 0.64 (t, J=6.8 Hz, 2H). MS (M+1): 209.1.
