Process for the synthesis of 2-(2,5-dimethyl-1H-pyrrol-1-yl)-1,3-propanediol and its substitued derivatives

The present invention relates to a process for the synthesis of molecules that have a pyrrole ring bonded to a diol. In particular, the invention relates to the synthesis of molecules that have the pyrrole ring and a diol derived from serinol by means of a process that does not demand the use of solvents or chemical catalysts. The process consists of a first reaction phase that takes place without any solvents and/or organic diluents, giving rise to an intermediate compound, and a second phase in which the intermediate compound is converted into the required compound by heating the reaction mixture to a temperature ranging from 100° to 200°C for an interval in the range of 1 to 500 minutes, or by adding a carbon allotrope or its derivatives.
