Abstract

The preparation of tritium labelled catechol by catalytic reduction of tetrabromocatechol is described. Recrystallization of catechol (U‐^3^H) after silica gel column purification gave 68% yield of the desired product with 98% purity as assayed by high performance liquid chromatography.

## Abstract The reaction conditions for the incorporation of tritium into zaleplon have been investigated. The methods studied were the catalytic isotope exchange reaction with tritium gas and catalytic isotope exchange reaction with tritiated water. The results showed that the latter method was th

## Abstract Mazindol was labeled with tritium in the 6,9 positions in low yield starting with dimethyl phthalate‐3,6‐^3^H which was prepared by reduction of dimethyl 3‐chlorophthalate with tritium gas using 10% palladium on charcoal as a catalyst. The labeled dimethyl phathalate was hydrolisized wi
