Procedure

0.1 g (0.37 mmol) of 2-(2-ethoxybenzyl)-4-(methylsulphanyl)-6-oxo-1,6-dihydro-5-pyrimidinecarbonitrile is heated with 0.13 g (0.99 mmol) of 2-(4-piperidinyl)ethan-1-ol in 3 ml of acetonitrile at 90° C. under argon for five days. After cooling to room temperature, the crude product is purified by preparative HPLC. 45 mg (43% of theory) of the title compound are obtained as a colourless solid.
