A mixture of 4.5 parts of 3-(2-hydroxyethyl)-1-methyl-2,4-(1H,3H)quinazolinedione, 8 parts of thionyl chloride and 75 parts of trichloromethane was stirred and refluxed for 5 hours. The reaction mixture was evaporated, yielding 4.5 parts (95%) of 3-(2-chloroethyl)-1-methyl-2,4(1H,3H)-quinazolinedione as a residue (intermediate 171).
