ABSTRACT:
A process for producing a compound of the formula: ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl group or an aralkyl group, and R.sup.2 is a hydrogen atom or a hydroxyl-protecting group, or a salt thereof, which comprises removing from a compound of the formula: ##STR2## wherein R.sup.3 is a hydrogen atom or a hydroxyl-protecting group, R.sup.4 and R.sup.5 which may be the same or different are N-protecting groups selected from the group consisting of lower alkyl groups and aralkyl groups, and X.sup..crclbar. is an anion, the N-protecting group(s), if necessary, together with the hydroxyl-protecting group.
