Procedure
To a solution of 6-(3,4-dimethoxyphenyl)-1-(2,3-epoxypropyl)-3-methyl-2,4(1H,3H)-pyrimidinedione (0.6 g) in ehtanol (20 ml) was added tert-butylamine (2 ml). The mixture was refluxed for 2.5 hours and evaporated in vacuo. The resulting syrup was triturated in a mixture of diethyl ether and diisopropyl ether to give 1-(3-tert-butylamino-2-hydroxy-1-propyl)-6-(3,4-dimethoxyphenyl)-3-methyl-2,4(1H,3H)pyrimidinedione (0.66 g).
