Reaction Steps

3.4 g of 1-(2-chloroethyl)-3-isobutyl-3-D-galactopyranosylurea are dissolved in a mixture of 80 ml of tetrahydrofuran and 80 ml of methylene chloride, and 15 g of sodium carbonate anhydrate are added thereto. 5 g of nitrogen tetroxide gas are introduced into the mixture for 10 minutes under ice-cooling. The mixture is treated in the same manner as described in Example 2. 3.0 g of 1-(2-chloroethyl)-1-nitroso-3-isobutyl-3-D-galactopyranosylurea are thereby obtained as a yellow powder.
