Thiouracil and uracil derivatives are among the bioactive molecules used in the treatment of many diseases, such as 6-propylthiouracil and 5-fluorouracil. A new synthesis method of 6-methylthiouracil and 6-methyluracil was developed in this study. Various 6-methylthiouracil and 6-methyluracil derivatives were obtained by reacting 2,2,6-trimethyl-4H-1,3-dioxin-4-one with thiourea and urea compounds in the presence of Yb(TFA)3 according to this new method. Optimization of this new method was performed. The structures of 6-methylthiouracil and 6-methyluracil derivatives were characterized.
