A solution of 1.2 g (3.0 mmol) of 2-[4-(N-benzyl-methylamino)-3-nitro-phenyl]-2-methyl-3-hydroxy-1-pyrrolidino-propan-1-one in 20 ml of tetrahydrofuran is combined at room temperature with 1.3 ml of (9.3 mmol) of triethylamine. Then 0.27 ml (3.5 mmol) of methanesulphonylchloride are added dropwise at 2-5° C.
