Application of 104-77-8, A common heterocyclic compound, 104-77-8, name is 3-Chloro-N,N-diethylpropan-1-amine, molecular formula is C7H16ClN, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Example 29 (346) Synthesis of N-(Toluene4-sulfonyl)-L-prolyl-4-[3-(N,N-diethylamino)propoxy]-L-phenylalanine Methyl Ester The methyl ester was prepared via O-alkylation of N-(toluene-4-sulfonyl)-L-prolyl-L-tyrosine methyl ester with 3-diethylaminopropyl chloride in refluxing 2-butanone in the presence of potassium carbonate and sodium iodide. NMR data was as follows: 1H NMR (DMSO-d6, 400 Mhz): delta=1.0 (6H, bs); 1.4-1.6 (4H, m); 1.85 (2H, m); 2.18 (3H, s); 2.5 (2H, bs); 2.5-2.8 (4H, bs); 2.9 (2H, m); 3.1 (1H, dd, J=8, 10, 8 Hz); 3.35 (1H, dd, J=8, 4, 8 Hz); 3.6 (3H, s); 3.94 (2H, t, J=6, 6 Hz); 4.1 (1H, m); 4.48 (1H, dd, J=8, 6, 8 Hz); 6.8 (2H, d, J=10 Hz); 7.1 (2H, d, J=10 Hz); 7.4 (2H, d, J=10 Hz); 7.7 (2H, d, J=10 Hz); 8.2 (1H, d, J=10 Hz). MS: +ESI, m/z 560.5 ([MH]+, 100%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
