Reaction Steps

Ethyl isocyanate (1.2 ml, 14.18 mmol) is added to 5-(4-methoxy-phenyl)-4-methyl-thiazol-2-ylamine (Example 28b) (1.56 g, 7.09 mmol) in dioxane (100 ml). After 5 hours at 85° C. the reaction mixture is concentrated to yield 1-ethyl-3-[5-(4-methoxy-phenyl)-4-methyl-thiazol-2-yl]urea as a brown solid.
