M. Prashad et al., A PRACTICAL SYNTHESIS OF SDZ WAG-994 BY SELECTIVE METHYLATION OF N-6-CYCLOHEXYLADENOSINE, Synthetic communications, 26(21), 1996, pp. 3967-3977
A selective 2'-O-methylation of N-6-cyclohexyladenosine (2) under phas
e-transfer catalysis conditions and a preferential crystallization of
N-6-cyclohexyl-2'-O-methyladenosine (1, SDZ WAG 994) from a mixture of
by-products is described. A plausible explanation for the selective c
rystallization of 1 as a hydrate is presented.
