4792-71-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4792-71-6,5,7-Dichloro-1H-indole-2-carboxylic acid,as a common compound, the synthetic route is as follows.
EXAMPLE 102 R-Methyl 2-[(5-7-dichloro-1H-indole-2-carbonyl)-amino]-3-phenyl-propionate From 5,7-dichloro-1H-indole-2-carboxylic acid and D-phenylalanine methyl ester. 1 H NMR (300 MHz, CDCl3) delta 3.25 (m, 2H), 3.80/3.95 (s, 3H), 5.10 (m, 1H), 6.62 (d, 6 Hz, 1H), 6.69 (d, 2 Hz, 1H), 7.10-7.15 (m, 2H), 7.25-7.35 (m, 3H), 7.50-7.56 (s, 1H), 9.35 (br, 1H).
As the paragraph descriping shows that 4792-71-6 is playing an increasingly important role.
