AbstractAbstract
[en] Non-active 5-formyluracil dissolved in 0.01 N to 1.0 N of hydrochloric acid is acted upon by gaseous carrier-free tritium at room temperature in the presence of a heterogeneous palladium/carrier catalyst, with advantage palladium on barium sulfate. The described procedure allows the preparation of [methyl-3H]thymine on a microscale, with a high molar activity in a single reaction stage with a high chemical (50-70%) and radiochemical (15-25%) yield. (J.P.)
