実験手順

A solution of 200 mg (0.70 mmol) of 4-(tetrahydropyranyloxy)methyl-2'-amino-1,1'-biphenyl (Example 1, Step N) and 0.40 mL of triethylamine in 10 mL of methylene chloride under a nitrogen atmosphere was treated with triphosgene (420 mg, 0.24 mmol). The reaction mixture was stirred at room temperature for 30 minutes when thin layer chromatography on silica (hexanethyl acetate; 2:1) revealed no remaining amine. The reaction mixture was evaporated under vacuum to yield the crude product which was used in the next step without purification.
