Treatment of 21 with 2,4,6-trisisopropyl benzenesulfonyl chloride followed by aq ammonia provided the corresponding cytidine derivative in 9% overall yield. Use of thionyl chloride gave extensive detritylation. (a) Martin, J. A; Bushnell, D. J.; Duncan, I. B.; Dunsdon, S. J.; Hall, M. J.; Machin, P. J.; Merrett, J. H.; Parkes, K. E. B.; Roberts, N.
