A process for the preparation of a compound of formula
in the form of a single stereoisomer, comprising deprotecting the amine group in an N-protected amino-hydroxy-cyclohexylsulfanyl-acetyl-mutilin of formula
wherein R is an amine protecting group in the form of a single stereoisomer,
and isolating a compound of formula I in the form of a single stereoisomer obtained from the reaction mixture; compounds obtainable by such processes, e.g. a compound of formula I in a crystalline form, or salts of a compound of formula I in crystalline form, and processes for the preparation of intermediates for the production of a compound of formula I.
