3-chloro-N′-hydroxybenzenecarboximidamide (54.3 mg, 0.32 mmol), 3-[3-cyclopropyl-2-(4-methoxy-phenyl)-3H-imidazol-4-yl]-propionic acidethyl ester (100 mg, 0.32 mmol) and sodium-tert-butoxide (30.6 mg, 0.32 mmol) were mixed with EtOH (1 ml) and toluene (1 ml), followed by stirring at 100° C. for 24 h. The mixture was then concentrated, in-vacuo, and the residue was purified via column chromatography using 50% EA in hex. and then triturated with Et2O to isolate the title compound (27 mg). 1H-NMR: 8.1 (m, 1H), 7.97 (dd, 1H), 7.64 (d, 2H), 7.47 (m, 2H), 6.96 (d, 2H), 6.88 (s, 1H), 3.87 (s, 3H), 3.37 (m, 4H), 3.24 (m, 1H), 1.06 (m 2H), 0.68 (m, 2H).
