Procedure

A mixture containing 11 g of the compound prepared in step B, 140 ml of carbon tetrachloride, 4.12 g of NBS and 0.4 g of benzoyl peroxide is refluxed for 3 hours. After it has returned to RT, it is filtered and the filtrate is then evaporated. The residue is taken up in 30 ml of isopropyl ether. The precipitate formed is filtered off and then dried under vacuum.
