Procedure

Methyl isocynate (20 g.) is added slowly, with stirring, to a filtered solution of 30 g. of xanthydrol in 100 ml. of anhydrous triethylamine. After standing for 40 minutes in a 20° C. water bath, the mixture is filtered. The collected solid is washed with anhydrous diethyl ether and dried in vacuo to give 9-(N-methylcarbamoyloxy)xanthene.
