Procedure

Methanesulfonyl chloride (0.21 mL) was added to a stirred solution of N-cyclopropyl-3-[3-[[(1R)-1-[2-(2-hydroxyethoxy)phenyl]propyl]amino]-2-oxo-1(2H)-pyrazinyl]-4-methyl-benzamide (410 mg) and triethylamine (0.5 mL) in dichloromethane (10 mL) at 0° C. The mixture was stirred for 1 h at 0° C. and 1 h at room temperature. Water was added and the organic phase was separated, (Na2SO4), filtered and concentrated in vacuo. The residue was treated with dichloromethane (10 mL) and pyrrolidine (0.73 mL) and the mixture was stirred at room temperature for 24 h. The mixture was concentrated in vacu. Purification by preparative HPLC (Gemini column, 0.1% ammonia: acetonitrile eluent) afforded the title compound as a solid (147 mg).
