Reaction Conditions

Reaction Steps

A solution of 5-(1-oxo-2-ethyl-6,7-dichloro-5-indanyloxymethyl)tetrazole (2.0 g.) in acetic acid (300 ml.) is warmed to 65° C. on a steam bath and treated during a 10-minute period with a solution of chlorine (700 mg.) in acetic acid (25 ml.). The reaction mixture is heated one hour at 100° C. and the solvent is distilled at reduced pressure to a volume of 50 ml. which on treatment with water affords 0.8 g. (36%) of 5-(1-oxo-2-ethyl-2,6,7-trichloro-5-indanyloxymethyl)tetrazole which melts at 128° C. after recrystallization from ethylacetate and hexane.
