Reaction Steps

(+,-)-N-(cis-2-(2-fluoro-5-butoxyvinyl-6-methoxymethoxy)-cyclopropyl)-N'-(5-chloropyrid-2-yl)-urea (Example 55) was dissolved in dioxane and a few drops of dilute hydrochloric acid was added. The solution was stirred for 15 minutes, was diluted water and evaporated. The residue was co-evaporated with water to yield the title product as a solid. 1 H-NMR CDCl3 1.3 (q, 1H) 1.5 (q, 1H) 2.1 (q, 1H) 2.5 (s, 3H) 3.4 (m, 1H) 3.5 (s, 3H) 5.1 (m, 2H) 6.8 (m, 2H) 7.4-7.6 (m, 2H) 7.8 (d, 1H) 9.1 (bs, 1H) 9.8 (bs, 1H).
