| Txoj Kev Purification | Qhuav 3,5-lutidine nrog sodium thiab fractionally distil nws los ntawm Todd kem (p 11) ntim nrog iav helices. Dissolve (100mL) hauv dilute HCl (1: 4) thiab chav distil no kom txog thaum 1L ntawm distillate tau sau. Tshaj conc NaOH ntxiv rau qhov seem uas yog rov ua dua chav distilled. Lub hauv paus yog muab rho tawm los ntawm distillate, siv diethyl ether. Cov extract yog qhuav dhau K2CO3, thiab distilled. Tom qab ntawd nws yog fractionally crystallized los ntawm ib nrab khov. Cov hydrochloride muaj m 229o (sublimes ntawm 190-231o), thiab cov picrate muaj m 242-243o(dec, los ntawm H2O), 249-250o(dec, los ntawm AcOH). [Beilstein 20 II 161, 20 III/IV 2788, 20/6 V 60.] |
