With phosphoric acid; In water; acetonitrile; | step (1) dissolved, filter:[0062] and take Belinostat Belinostat isomer mixture III (E / Z = 52/48) lg, dissolved 0 ? 1% phosphoric acid solution / acetonitrile (85/15) mixture of 250ml, and will Belinostat Belinostat mixture of isomers dissolved, dissolved organic 0. 45 mu m filter membrane to obtain a solution.[0063] separation and purification steps:[0064] The step (1) was injected into all reversed phase high performance preparative liquid chromatography, mobile phase consisted of 0.1% phosphoric acid solution (Alpha) - acetonitrile composition, flow rate of 80ml / min, UV detector line detection, detection wavelength of 221nm.[65] gradient elution was carried out as follows:[0067] Preparation of Belinostat targeted isomer eluted fractions were collected to give Belinostat isomer solution.[0068] Step (3) Product recycling:[0069] The step high performance preparative liquid chromatography of the resulting solution Belinostat isomerAcetonitrile by distillation (0. 08-0. 09MPa, 40-50 C) was removed with 500ml of methylene chloride extraction, distillation(0 · 08-0 · 09MPa, 35-45 C) methylene chloride was removed to obtain Belinostat isomers. The total yield of 35.2%,Belinostat isomer by HPLC purity was 99.5% |
