The invention is a method and related precursor for preparing
18
F-FLT. The precursor has a butoxycarbonyl protecting group at the 5′-position that results in low amounts of chromophoric byproducts being formed during deprotection. The method for preparing
18
F-FLT is efficient and makes the final purification step less complicated.
