Procedure
2-chloro-6-fluorobenzaldehyde (Aldrich), was converted to 2-chloro-6-fluorostyrene according to the method described in Example 377 of WO 93/03022 and then to cis-2-(2-chloro-6-fluorophenyl) cyclopropylisocyanate analogously to the method described in Example 348 of WO 93/03022. This compound was then condensed with 2-amino-5-cyanopyridine of Example 41 in a manner analogous to the method in Example 7 to provide N-(cis-2-(2-chloro-6-fluorophenyl)-cyclopropyl)-N'-(5-cyanopyrid-2-yl)-urea: Mp 189° C. 1H-NMR (250 MHz, DMSO-d6): 1.2 (m, 1H), 1.45-1.55 (m, 1H), 2.2-2.3 (m, 1H), 3.3-3.4 (m, 1H), 7.35-7.6 (m, 4H), 7.9-8.1 (m, 2H), 9.5 (s, 1H).
