Synthesis of carbon‐14 labelled 2‐amino‐9‐(3‐hydroxymethyl‐4‐isopropoxycarbonyloxybut‐1‐yl)purine (SK1875), a potential prodrug of penciclovir
摘要:
The synthesis of C-14-2-amino-9-(3-hydroxymethyl-4-isopropoxycarbonyloxy-but-1-yl)purine from [1-C-14] diethyl malonate is described. The overall radiochemical yield of the product in a nine-step sequence was 16.1%, and the compound's radiochemical purity was 98.5%.
