Procedure

Analogously to the compound in Example 96A, 181 mg (1.62 mmol) of 4-hydroxymethyl-5-methyl-1H-imidazole, 381 mg (1.62 mmol) of 5-(4-chlorophenyl)-4-cyclopropyl-2,4-dihydro-3H-1,2,4-triazol-3-one [preparation according to WO 2007/134862 Example 36A] and 670 mg (4.85 mmol) of potassium carbonate were reacted with one another. This gave 180 mg (47% of theory) of the target compound in a purity of 76%.
