실험 절차

(3S)-3-(Dimethylamino)pyrrolidine (88 μl, 0.695 mmol) and triethylamine (97 μl, 0.695 mmol) were added to a dimethyl sulfoxide (4 ml) solution of 7-fluoro-2-(2-furylmethyl)-5-methyl-6-phenyl-1,3-benzoxazole-4-carbonitrile (I-271) (154 mg, 0.463 mmol), followed by stirring in an oil bath at 95° C. for 1 hour. The reaction liquid was concentrated under reduced pressure, then the residue was dissolved in ethyl acetate, and washed with water and saturated brine. After drying over anhydrous sodium sulfate, the insoluble matter was separated by filtration, and the residue obtained by concentration was purified by silica gel column chromatography and preparative TLC (eluent, chloroform:methanol=20:1, v/v) to obtain the entitled compound (27 mg, 14%) as a pale brown foamy substance.
