Procedure

The invention relates to a process for the preparation of a new crystalline monohydrate of 1-(3', 4'-diethoxy-benzyl-6, 7-diethoxy-3,4-dihydro-isoquinolinium-theophylline-7-acetate and if desired of pure 1-(3', 4'-diethoxy-benzyl)-6,7-diethoxy-3, 4-dihydro-isoquinolinium-theophylline-7-acetate free of contaminating oxidation products which comprises reacting 1-(3',4'-diethoxy-benzyl)-6,7-diethoxy-3,4-dihydro-isoquinolinium with theophylline-7-acetate acid in the presence of water and one or more organic solvent(s) and if desired dehydrating the 1-(3',4'-diethoxy-benzyl) 6,7-diethoxy-3,4-dihydro-isoquinolinium-theophylline-7-acetate-monohydrate thus obtained.
