✦ Synopsis
Synthetic procedures for tritiation of a retinoidal benzoic acid derivative, (E)-4-[ 2-( 5,6 , 7,8-n?trahydro-5,5,8,8-tetramethyl-2-naphthalenyl-6, 7-'ii2 1-1propenyll-benzoic acid, (TTNPB), are described. Tritium was introduced by catalytic hydrogenation. The final product, TTNPB-3H2 (2). had a specific activity of 24.1 Ci/mmole and a radiochemical purity of 95.6%.

## Abstract A rapid method of no‐carrier‐added radiobrominations of A‐ring estrogens has been demonstrated. The method employs N‐chlorosuccinimide and high specific activity sodium bromide‐77 to generate an electrophilic brominating agent, which when reacted with phenolic steroids, yields three pri
