Procedure

2-Dimethylamino-4-phenylpyrimidine-5-carboxylic acid (1.22 g, 5 mmol) is dissolved in tetrahydrofuran (60 ml). After 5 minutes of stirring to the solution are added: L-phenylephrine hydrochloride (1.22 g, 6 mmol) in tetrahydrofuran (50 ml), after another 5 minutes of stirring the N-methylmorpholine (1.21 g, 12 mmol) and after 2 minutes of stirring the 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (1.66 g, 6 mmol). The reaction mixture is stirred for 2 hours at room temperature, then heated at reflux temperature for 2 hours. The solvent is removed in vacuum. To the residue water (50 ml) is added, and the mixture is extracted with chloroform (75 ml), the extract is washed with 10% sodium carbonate solution (35 ml), with water (35 ml), dried over sodium sulphate and evaporated. The residue is chromatographed on silicagel using chloroform-methanol 100/1-100/5 mixture eluent. 0.36 g of the title compound is obtained, m.p.: 79-81° C.
