実験手順
To a solution of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(1H-indol-3-ylmethyl)-4-(4-pentanon-1-yl)piperazine (1.37 g) in toluene (15 mL) was added drop-wise methyl vinyl ketone (0.3 g). After 2.5 h at room temperature the solution was concentrated to afford crude (2R)-1-[3,5-bis(trifluoromethyl)-benzoyl]-2-(1H-indol-3-ylmethyl)-4-(3-butanon-1-yl)piperazine which was used as such. Rf 0.55 (CH2Cl2/MeOH 95/5).
