反応手順

To a solution of crude 1-[3-((S)-4-hydroxy-6-aza-spiro[2,5]oct-6-yl)-propyl]-3-methyl-piperazin-2-one dihydrochloride (example 38; 0.03 g, 0.1 mmol) in N,N-dimethylformamide (0.8 ml) was added 4-chloro-3-fluorocinnamic acid (0.02 g, 0.1 mmol), triethylamine (0.05 ml, 0.4 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate (0.04 g, 0.1 mmol) and the reaction shaken for 1 h, after which time the reaction mixture was directly purified by preparative HPLC. This afforded the titled product as a colorless gum. MS (ISP)=464.3 (M+H)+.
