The starting material is prepared as follows: To 39,230 ml of 2 N hydrochloric acid, 7,500 g of aminoacetaldehyde dimethylacetal are added during 45 minutes while stirring under nitrogen, followed by 6,932 g of potassium thiocyanate, which are added all at once. The mixture is heated to 98°, stirred for 2 hours and allowed to cool to room temperature overnight. The resulting suspension is stirred and cooled to 5°, filtered and the residue dried at 60°/5 mmHg, to yield the imidazole-2-thiol melting at 224°-226°.
