A new practical approach to prepare 1,3-(diethoxymethyl)-5-N,N-dimethylamino-6-methyluracil (5) has been realized from 6-methyluracil (1). Compound 5 is a key intermediate material in the synthesis of HIV-1 RT and methionine synthase inhibitors. 6-Methyluracil (1) reacted with HNO3-P2O5 giving 5-nitro-6-methyluracil (2), which alky-lated at N1,N3 through reaction with ethoxymethyl chloride to give 3. Compound 3 was then reduced through treatment with HCOONH4-Pd/C and the derived C-5 amino group reacted with CH3I to convert into compound 5 in good yield.

Key words: 1,3-(diethoxymethyl)-5-amino-6- methyluracil, 1,3-(diethoxymethyl)-5-N,N-dimethylamino-6-methyluracil, 5-nitro-6-methyluracil
