실험 절차

To a mixture of {3-methoxy-4-[(2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]phenyl}methanol (0.93 g), 3-hydroxy-1-phenyl-1H-pyrazole-4-carbaldehyde (0.58 g), tributylphosphine (0.85 g) and tetrahydrofuran (100 mL) was added 1,1′-(azodicarbonyl)dipiperidine (1.06 g) at room temperature, and the mixture was stirred for 15 hrs. The precipitated crystals were removed by filtration and the filtrate was concentrated. The residue was subjected to silica gel column chromatography to give 3-({3-methoxy-4-[(2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]benzyl}oxy)-1-phenyl-1H-pyrazole-4-carbaldehyde as crystals (0.83 g, yield 58%) from a fraction eluted with ethyl acetate-hexane (2:3, v/v). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 128-129° C.
