چکیده
We report here the structure of the title compound, (I) (Fig. 1), which was prepared by microwave irradiation of a twocomponent mixture of a 6-aminopyrimidine and the condensation product formed from dimedone and formaldehyde. By contrast a similar reaction between 6-aminopyrimidines, 5,5dimethylcyclohexane-1,3-dione and a large excess of formaldehyde yielded spiranopyridopyrimidines (Quiroga et al., 2006).
