실험 절차

The THF solution (2 ml) including 2,6-bis[(4S)-isopropyl-2-oxazoline-2-yl]pyridine (0.05 mmol, 15.2 mg) and copper chloride (II) (0.05 mmol, 6.9 mg) was stirred for a day at room temperature. After the reaction mixture was cooled to 0° C., the THF solution (2 ml) of 5′-O-[bis(4-methoxyphenyl)phenylmethyl]uridine (0.5 mmol, 274 mg) and the THF solution (2 ml) of phenyl isocyanate (0.5 mmol, 59.6 mg) are added thereto. After the mixture was continuously stirred for two hours at 0° C., the mixture was analyzed with high-performance liquid chromatography. As a result, it was found that 5′-O-[bis(4-methoxyphenyl)phenylmethyl]-2′-O-phenylcarbamoyl-uridine and 5′-O-[bis(4-methoxyphenyl)phenylmethyl]-3′-O-phenylcarbamoyl-uridine were produced at the ratio of 94:6, and the transformation ratio of the reaction was not less than 99%.
