実験手順

2-Methyl-2-[3-(3-{4-[7-(2-morpholin-4-yl-ethoxy)-benzo[d]imidazo[2,1-b]thiazol-2-yl]-phenyl}-ureido)-isoxazol-5-yl]-propionic acid (I-5) is prepared by following a general procedure given in J. Org. Chem. 2002, 67, 411. To a stirred solution of 1-[5-(1,1-dimethyl-2-oxo-ethyl)-isoxazol-3-yl]-3-{4-[7-(2-morpholin-4-yl-ethoxy)-benzo[d]imidazo[2,1-b]thiazol-2-yl]-phenyl}-urea (I-4a) (1 equivalent) in a 5:1 mixture of tert-butanol and water at rt are added sequentially dihydrogen sodium phosphate (3 equivalents), 2-methyl-2-butene (6 equivalents), and sodium chlorite (1 to 1.5 equivalents) and the mixture is stirred at rt until the reaction is substantially complete as monitored by LCMS or TLC. The mixture is concentrated under reduced pressure and the residue is partitioned between water and either dichloromethane or a mixture of isopropanol and dichloromethane. The separated aqueous layer is further extracted with dichloromethane or a mixture of isopropanol and dichloromethane. The combined organic layers are washed with water or brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The residue is purified by preparative reverse-phase HPLC or silica gel flash chromatography to afford 2-methyl-2-[3-(3-{4-[7-(2-morpholin-4-yl-ethoxy)-benzo[d]imidazo[2,1-b]thiazol-2-yl]-phenyl}-ureido)-isoxazol-5-yl]-propionic acid (I-5).
