Procedure
A mixture of 0.23 g of 4-cyclopropylmethoxy-2,5-dimethylphenylamine and 10 mL of N,N-dimethylformamide dimethylacetal was stirred under heating and refluxing for 10 hours. The cooled reaction mixture was concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to obtain 0.18 g of N′-(4-cyclopropylmethoxy-2,5-dimethylphenyl)-N,N-dimethylformamidine (Compound of Present Invention (1-17)).
