Embodiment 1

[0032]Take resveratrol 5g (0.022mol), NaOH 2.64g (0.066mol), water 80mL, succinic anhydride 2.2g (0.022mol). Stir the reaction at room temperature for 30 minutes, and acidify the reaction solution with 100 mL of dilute hydrochloric acid (1 mol / L). Extracted with ethyl acetate, anhydrous Na 2 SO 4 dry. The crude product was subjected to silica gel column chromatography (developing solvent: ethyl acetate:petroleum ether:acetic acid=1:1:0.01, v:v) to obtain Compound A. Take compound A 1.47g (4.5mmol), DCC 1.42g (6.9mmol), THF 25mL, delavirdine intermediate 1.3g (3.4mmol). The reaction was stirred at room temperature for 5 h, and DCU was removed by filtration. The crude product was subjected to silica gel column chromatography (developing solvent: chloroform:methanol=20:1, v:v) to obtain 1.1g (46%) of the compound risdelasine such as figure 1 shown.

Embodiment 2

[0034] Take delavirdine 1g (2.65mmol), THF 10mL, succinic anhydride 0.265g (2.65mmol). Stir the reaction at room temperature for 30 min, add 200 mL of diethyl ether to precipitate, filter, and dry to obtain 1.15 mg (91%) of Compound B. Take compound B 1.265g (2.65mmol), DCC 0.57g (2.78mmol), THF 10mL, DMAP 0.1g (0.82mmol), resveratrol 0.63g (2.78mmol). The reaction was stirred at room temperature for 5 h, and DCU was removed by filtration. The crude product was subjected to silica gel column chromatography (developing solvent: chloroform:methanol=20:1, v:v) to obtain the compound risdelatin. Such as figure 2 shown.

Abstract

This invention discloses a method for synthesizing resdelasu from delaviradine intermediate and resveratrol. The method comprises: amidating succinic anhydrate and delaviradine intermediate, and esterifying with resveratrol to obtain resdelasu; or esterifying succinic anhydrate with resveratrol, and amidating with delaviradine intermediate to obtain resdelasu. Resdelasu has the same magnitude order of in vitro bioactivity with anti-HIV drug delaviradine, thus can be used as a new anti-HIV drug.
