Procedure

(S)—N-(3,5-dimethylphenyl)pyrrolidine-2-carboxamide hydrochloride (18, 3.299 g; 10.7 mmol) is dissolved in MeCN (40 ml) at rt and DIPEA (4.4 g; 34 mmol) is slowly added over 10 minutes followed by the careful addition of commercially available 4-methoxybenzenesulfonyl chloride (19, 2.8 g; 13.6 mmol). The reaction mixture is stirred for 12 h at rt followed by the addition of brine (50 ml) and the extraction of the product with DCM (3×35 ml). The combined organic layers are dried over MgSO4, filtered and concentrated under reduced pressure to give 3.95 g (95%) of (S)—N-(3,5-dimethylphenyl)-1-((4-methoxyphenyl)sulfonyl)-pyrrolidine-2-carboxamide (Example 26) as amorphous solid. LC-MS: tR=0.83 min; [M+H]+=389.3.
