Procedure

5-(3-methyl-4-isothiazolyl)-2,4(1H,3H)-pyrimidinedione (Pre 47, 0.126 mmol) was dissolved in N,N-Dimethylformamide (DMF) (1 ml). TRIETHYLAMINE (0.021 ml, 0.151 mmol) was added and the mixture was stirred at room temperature for 5 minutes. Acrolein (8.42 μl, 0.126 mmol) was added and the mixture was stirred at room temperature monitoring the reaction progression by LCMS. After 7 hrs Acrolein (3 μl) was added and the mixture was stirred at rt overnight.
