Procedure

According to Scheme 2 Step 1: A solution of 4,4-dimethylcyclohexane-1,3-dione (157 mmol, 22 g) and of 1,1-dimethoxy-N,N-dimethylmethanamine (235 mmol, 31.3 mL) was stirred at room temperature for 1 hour. After evaporation and trituration in petroleum ether, 29.2 g (150 mmol, 95%) of 2-((dimethylamino)methylene)-4,4-dimethylcyclohexane-1,3-dione were obtained as a pale orange solid.
