Procedure

2-Methyl-5-methoxyaniline (0.3 mole), the dimethyl acetal of 2-chloroacetaldehyde (0.3 mole) and sodium carbonate (20 grams) are charged into a glass reaction flask equipped with a mechanical stirrer. thermometer and reflux condenser. The reaction mixture is heated to about 150°C for a period of about 8 hours. After this time the mixture is filtered and the filtrate is distilled to yield the desired product the dimethyl acetal of 2-(2-methyl-5-methoxyanilino)acetaldehyde.
