Procedure
To a stirred solution of (E)-4-chloro-N-((dimethylamino)methylene)benzamide (9.4 g, 44.6 mmol) in acetic Acid (13.5 ml) was added hydrazine hydrate (1.524 ml, 49.1 mmol). The reaction mixture immediately solidified and was heated to 120° C. for 2 hours. Whereupon was cooled to room temperature and azeotroped with toluene. The crystalline residue was stirred with water for a while. The precipitate was filtered off, washed with water and dried under vacuum. (Yield: 7.27 g, 91%).
