Versuchsvorschrift

3-Iodo-4-methylbenzoic acid (2.5 g, 9.5 mmol, 1 eq), 1-(pyridin-2-yl)cyclopropanamine (1.41 g, 10.4 mmol, 1.1 eq), EDCI.HCl (2.1 g, 11.4 mmol, 1.2 eq), HOBT (1.5 g, 11.4 mmol, 1.2 eq) and DIPEA (4.9 ml, 28.62 mmol, 3 eq) were dissolved in DCM and the above solution was stirred at room temperature for 18 h. Water was added and product was extracted with DCM. The organic layer was concentrated and the crude product crystallized using dichloromethane and hexane. Yield: 2.3 g (55%). 1HNMR (400 MHz, DMSO-d6): δ 1.26 (m, 2H), 1.53 (m, 2H), 2.43 (s, 3H), 7.13 (m, 1H), 7.29 (d, J=8.00 Hz, 1H), 7.44 (d, 1H), 7.67 (t, J=3.46 Hz, 1H), 7.87 (d, J=3.24 Hz, 1H), 8.38 (s, 1H), 8.44 (d, J=1.10 Hz, 1H), 9.29 (s, 1H).
