Synthesis of [8-3H]Pentostatin

Starting from 3‐(2‐deoxy‐β‐D‐erythro‐pentofuranosyl)‐6,7‐dihydroimidazo[4,5‐d][1,3]diazepin‐8(3H)‐one (4), the synthesis of both the R‐and S‐isomers of [8‐3H]pentostatin has been achieved. The separation of the desired R‐isomer in Ca. 24% overall chemical yield from the R, S‐mixture was effected by preparative reverse‐phase chromatography utilizing a C18 stationary support. Crystalline product of high specific activity (227 mCi/mmole) was obtained.
