合成路线1
The iodination of 1H-pyrazolo[3,4-d]pyrimidine-4-amine (I) with N-yodosuccinimide (NIS) gives 3-iodo-1H-pyrazolo[3,4-d]pyrimidine-4-amine (II), which is condensed with 1-O-acetyl-2,3,5-tri-O-benzoyl-D-ribofuranose (III) by means of BF3/ethyl ether in nitromethane to yield the benzoylated adduct (IV). Finally this compound is deprotected with sodium methoxide.
