5-position and side chains at the 1- and 6-positions were prepared. The three types of mono-bromo derivatives are: 1-(bromoalkyl)-3,6-dimethyl- 3a-d, 5-bromo-3,6-dimethyl-1-(hydroxyalkyl)- 4a-d, and 1-(acetoxyalkyl)-5-bromo-3,6-dimethyl-2,4(1H,3H)-pyrimidinediones 11a-d. The three types of dibromo derivatives are: 5-bromo-1-(bromoalkyl)-3,6-dimethyl- Sa-d, 1-(acetoxyalkyl)-5-bromo-6-bromomethyl- 8a, 8c
