Procedure
To a mixture of 5-(4'-hydroxymethyl-1,1'-biphenyl-2-yl)-2-triphenylmethyl-2H-tetrazole (0.01 m=4.90 g) and potassium carbonate (0.05 m=6.90 g) stirred in 50 mL N,N-dimethylacetamide chilled at 1° C. was added a total of 3.34 g (0.024 m) of methanesulfonyl chloride in 0 portions over 6 hours. The progress of the reaction was monitored by thin layer chromatography or HPLC. The title compound was formed in better than 90% in the mixture which was used in the next example.
