With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42923-79-5,7-Nitro-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.
2-Methanesulfonyl-l52,354-tetrahydro-isoquinolin-7-ylamine was prepared as follows: A solution of l5253,4-tetrahydro-isoquinolin-7-ylamine (1.255g)[ prepared from 1,2,3,4-tetrahydroisoquinoline according to J. Med. Chem., 2003, 46(5), pp831- 7.], NEt3 (l.lmL) and methanesulfonylchloride (0.6mL) in dry CH2Cl2 (2OmL) was stiired at R.T. overnight. Aqueous work-up followed by purification on silica gave 2- methanesulfonyl-7-nitro-l,25354-tetrahydro-isoquinoline (1.435g).
The synthetic route of 42923-79-5 has been constantly updated, and we look forward to future research findings.
