N-(2,4-Dinitrophenyl)-4-amino-n-butyl aldehyde 3 was obtained with high yield of 80% when N-(2,4-dinitrophenyl)-L-proline 1 reacted with SOCl₂ at room temperature.However, the anticipated product N-(2,4-dinitrophenyl)-tetrahydropyrrolyl-2-(4-methylthiophenyl) ketone 2 did not be produced.The mechanism was discussed in this article.
- L-Proline,
- 1-fluoro-2,4-dinitrobenzene(FDNB),
- N-(2,4-dinitrophenyl)-4-amino-n-butylaldehyde
