Participants

Reaction Steps

A solution of (S)-2-amino-N-(3,4-dimethyl-phenyl)-2-phenyl-N-[2-(6-trifluoromethyl-pyridin-3-yl)-ethyl]-acetamide hydrochloride (40 mg, 0.086 mmol, derived from example 1) in dry CH2Cl2 (1.5 mL) was treated with methanesulphonyl chloride (10 mg, 0.087 mmol) under Argon and the mixture stirred at ambient temperature for 30 min then quenched with aqueous Na2CO3 (2 M, 1 mL), concentrated, then redissolved in EtOAc (15 mL) and washed with aqueous Na2CO3 (2 M, 3×15 mL). The combined aqueous layers were extracted with EtOAc (15 mL) and the combined organic layers dried over sodium sulfate. Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=95:5 to 60:40) afforded the title compound (42 mg, 96%) as a light yellow oil. MS m/e: 506.1 [M+H]+.
