With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42923-77-3,6-Methoxy-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,42923-77-3
0.5 g of 6-methoxy-1,2,3,4-tetrahydroisoquinoline was loaded in 20 mL of DMF in a flask in nitrogen atmosphere, followed by stifling. 1.1 g of cesiumcarbonate was added thereto at room temperature. 30 minutes later, 1.0 g of (S)-ethyl 3-(4-(4-(2-(methylsulfonyloxy)ethyl)benzyloxy)phenyl)hex-4-inoate prepared in Manufacturing Example 16 was added thereto, followed by stirring at room temperature for 12 hours. Upon completion of the reaction, distilled water was slowly added thereto, followed by extraction using ethylacetate. The extract was washed with brine, dried over anhydrous MgSO4, and concentrated. Then, silica gel column chromatography was performed to give the target compound. (0493) 1H NMR (400 MHz, CDCl3): delta 7.35 (2H, d), 7.30 (2H, d), 7.23 (2H, d), 7.00 (1H, d), 6.85 (2H, d), 6.80 (1H, d), 6.70 (1H, d), 5.00 (2H, s), 4.30 (2H, m), 4.13 (2H, m) 4.03 (1H, t), 3.80 (3H, s), 3.58 (6H, m), 3.30 (2H, s), 2.78 (2H, m), 1.86 (3H, d), 1.28 (3H, m).
The synthetic route of 42923-77-3 has been constantly updated, and we look forward to future research findings.
