실험 절차

A solution of 9H-fluoren-9-ylmethyl[6-(aminocarbothioyl)-4-butoxy-2-isobutyl-1-oxo-1,2-dihydro-3-isoquinolinyl]methylcarbamate (2.33 g, 4 mmol) and ethyl 2-chloroacetate (1.32 g, 8 mmol) in ethanol (20 ml) was refluxed under heating for 10 h. The resulting reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give ethyl 2-[4-butoxy-3-({[(9H-fluoren-9-ylmethoxy)carbonyl]amino}methyl)-2-isobutyl-1-oxo-1,2-dihydro-6-isoquinolinyl]-4methyl-1,3-thiazole-5-carboxylate (1.81 g, 65.3%) as crystals.
