실험 절차

The procedure of Example 1 was repeated, except that 10500 g (111.6 moles) of phenol was substituted for o-cresol. The crude crystals that separated out were rinsed with methylene chloride; after airdrying they weighed 5170 g or 87% of theoretical. Recrystallization from methanol-water yielded pure CDP, mp 188-189° C., that was 99.8% pure by gas chromatography.
