Definition

ChEBI: An organochlorine compound that is urea in which the two hydrogens on one of the amino groups are replaced by nitroso and 2-chloroethyl groups and one hydrogen from the other amino group is replaced by a 4-amino-2-methylpyrimidin-5-ylmethyl] group. An anti eoplastic agent especially effective against malignant brain tumors.

Manufacturing Process

0.4 g of sodium nitrite was added with stirring, at 0°C to 5°C, to a solution of 450 mg of 1-(2-chloroethyl)-3-[(2-methyl-4-aminopyridin-5-yl)methyl]urea in 8 ml of 5% hydrochloric acid, and the reaction mixture was then stirred at 0°C to 10°C for an additional 1.5 hours.
After completion of the reaction, the reaction mixture was made alkaline by the addition of sodium carbonate, whereupon crystals separated out in situ. The crystals were recovered by filtration, washed with water and then recrystallized from 6 ml of ethanol, to give 0.1 g of the pale yellow pure desired product having a decomposition point of 125°C.

Therapeutic Function

Antitumor, Antileukemic
