There is disclosed an improved process for the preparation of 1,3-bis(alkoxyalkyl)- and 1,3-bis(benzyloxyalkyl)-5,5-disubstituted barbituric acid derivatives, such as 1,3-bis(methoxymethyl)phenobarbital, by reacting e.g., phenobarbital, preferably, a multiple molar excess of dimethoxymethane and an at least equimolar amount of anhydrous stannic chloride based on the amount of phenobarbital.
