Title:
METHOD FOR PREPARING RADIOLABELED THYMIDINE HAVING LOW CHROMOPHORIC BYPRODUCTS
Document Type and Number:
WIPO Patent Application WO2005058247
Kind Code:
A3
Abstract:
The invention is a method and related precursor for preparing 18F-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 18F-FLT is efficient and makes the final purification step less complicated.
