| Product | 4-(2,3-Dihydro-1H-perimidin-2-yl)-N,N-dimethylaniline | HCID 256660 | 65.7% |
Reaction Steps
A solution of 3.2 g (0.02 mole) of 1,8-diaminonaphthalene and 3.0 g (0.02 mole) of p-dimethylaminobenzaldehyde in 35 ml of ethanol was refluxed for 2 hours. After cooling, the resulting precipitate was filtered and recrystallized from ethanol. There were obtained 3.8 g of 2-(p-dimethylaminophenyl)-2,3-dihydroperimidine as colorless crystals, m.p. 165°-166° C. (Compound No. 18).
