1.00 g (3.59 mmol) 3-Bromomethyl-5-(5-chloro-thiophen-2-yl)-isoxazole and 503.3 mg (3.59 mmol) urotropin were dissolved in 40 mL EtOH. The reaction mixture was stirred at room temperature for 16 h. The next day 3 mL of a conc. HCl-solution were added and the resulting mixture was refluxed for 45 minutes. After cooling the precipitate was filtered off and washed with water. The white crystalline material was dried under reduced pressure at 40° C.
