Versuchsvorschrift

tris(Dibenzylideneacetone)dipalladium (32 mg), 2-(di-tert-butylphosphino)biphenyl (21 mg) and sodium tert-butoxide (73 mg) were added to a 20 mL screw cap test tube substituted with nitrogen, and a solution of 2-[(4-{2-[(4-bromobenzyl)(5-ethylpyrimidin-2-yl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester (400 mg) synthesized in Example 402-1 and morpholine (91 mg) in toluene (1.4 mL) was added thereto. The test tube was capped, and stirred at 110° C. for 8 hr. After cooling to room temperature, the solution was directly purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=3:1 to 2:1) to give the title compound (200 mg) as a colorless oil.
