Procedure
A solution of [6-chloro-2-trifluoromethyl-7-(2,4,6-trimethyl-phenyl)-7H-imidazo[1,2-a]imidazol-3-yl]-methanol (614.8 mg, 1.718 mmol) and thionyl chloride (1.25 mL) in dichloromethane was stirred at 0° C. for 15 min. Thionyl chloride and the solvent were removed in vacuo and the residue was dried under high vacuum to yield the desired product as a yellow solid (646.3 mg, 100%). LC/MS: tR=1.46 min., MS: [MH−Cl+OMe]=373.
