PROCESS FOR THE PREPARATION OF CLADRIBINE

A process for the preparation of cladribine of API grade is provided by direct coupling of O-protected 2-deoxy-ribofuranose with silylated 2-chloroadenine followed by deprotection of the resultant protected nucleoside in a separate step and then a purification step. Following the coupling, the desired N-9-glycosylated β-anomer of the nucleoside is directly isolated as a solid from the coupling reaction mixture by filtration in relatively high purity and yield, and it does not require purification.
