A mixture of 2-methyl-5-(5-methyl-[1,3,4]oxadiazol-2-yl)-phenol (0.65 g; 3.42 mmol) (from Example 11 supra) and 4-methoxybenzylamine (3.10 g; 22.6 mmol) (Aldrich) in a sealed reaction vessel was heated in an oil bath at 150-155° C. for 42 hours. The reaction mixture was cooled to room temperature and diluted with dichloromethane and hexanes, forcing the product to precipitate out of solution. The crude solid was collected by filtration and then precipitated again from a dichloromethane-methanol solution as the solvent was evaporated off. The solid was collected and dried, to give 5-[4-(4-methoxy-benzyl)-5-methyl-4H-[1,2,4]triazol-3-yl]-2-methyl-phenol. (Yield 0.849 g, 76.3%).
