Reaction Steps

The title compound is prepared following substantially the same procedure described in Example 5, Step G, using the following substances: [1'-oxo-6',7'-dichlorospiro(cyclopentane-1,2'-indan)-5'-yloxy]acetonitrile (5.3 g.), sodium azide (1.44 g.), ammonium chloride (1.14 g.) and dimethylformamide (35 ml.). This procedure affords 5.0 g. (83%) of 5-[1'-oxo-6',7'-dichlorospiro(cyclopentane-1,2'-indan)5'-yloxymethyl]tetrazole which after recrystallization from acetonitrile melts at 191°C.
