Procedure

To a solution containing 1 g (10.4 mmol) of 1H-imidazole-4-carbaldehyde and 3.18 g (11.4 mmol) of trityl chloride suspended in 28 ml of acetonitrile are added dropwise 2.5 ml (17.7 mmol) of triethylamine. After stirring for 2 hours at room temperature, 30 ml of water are added and the crude reaction product is filtered. 3.2 g in the form of a beige-coloured powder are obtained and used in the following step without further purification.
