Jp. Reddy et al., INDEPENDENT SYNTHESIS AND FATE STUDIES OF IMPURITIES IN-PROCESS INTERMEDIATES OF THE ANTI-AIDS DRUG D4T, Organic process research & development, 2(3), 1998, pp. 203-207
Impurities in isolated intermediates in a process to prepare d4T were
identified, independently synthesized, and then taken through the proc
ess to determine their ultimate fate. Some of the products from these
fate studies were also independently synthesized and used in the valid
ation of impurity assay methods.
