実験手順

Sumatriptan base ((2.29g; 7.75 mmol) was dissolved in boiling ethyl acetate (300 mL) with stirring. Capric acid (1.33 g; 7.75 mmol) was dissolved in ethyl acetate (10 mL) and added to the sumatriptan base solution in one portion. The hot solution was stirred for a further 10 minutes and allowed to cool to room temperature. Evaporation of the solvent by rotary evaporation rave a pale yellow oil. Hexane (50 mL) was added and a white precipitate formed that was filtered off under vacuum. The precipitate was washed with hexane and allowed to dry at room temperature to give sumatriptan caprate as a pale yellow solid (2.79 g; 77.4%). The sumatriptan caprate was characterised by DSC and FT-IR. DSC gave a single, sharp endotherm with the onset at 94.6° C. The FT-IR differed significantly from that of the sumatriptan base.
