Synthetic Route of 1533519-84-4, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 1533519-84-4, name is 4-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione, molecular formula is C15H13N3S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Example 8. Preparation of methyl 2-((4-(4-cyclopropylnaphthalen-l-yl)-4H-l,2,4-triazol-3-yl)thio)acetate [073] To a round bottom flask added 4-(4-cyclopropyl-l-yl)-4H-l, 2,4-triazole-3-thiophenol (54.0 g), acetone/water (500 mL/25 mL), methyl chloroacetate (17.8 mL) and potassium carbonate (33.5 g) to form a mixture, the mixture was heated to about 40C, after stirred for about 6 hours, the mixture was cooled to room temperature (about 19C), then was added water (about 400 mL), stirred for about 5 minutes followed by removing acetone, filtered, the filter cake was washed with water and dried in vacuum at about 50C for about 12 hours to obtain methyl 2-((4-(4-cyclopropylnaphthalen-l-yl)-4H-l,2,4-triazol-3-yl)thio)acetate 65.0 g, yield 90%. LC-Ms: m/z (ESI): 402 (M+H)+, 1H MR (400 MHz, CDC13): delta 8.54 (d, J=8.0 Hz, 1 H), 8.32 (s, 1 H), 7.66 (m, 1 H), 7.54 (m, 1 H), 7.34-7.41 (m, 5 H), 7.23 (m, 1 H), 7.10 (m, 2H), 4.30 (dd, J=8.0, 12 Hz, 2 H), 2.43 (m, 1 H), 1.17 (m, 2 H), 0.86 (m, 2 H).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 4-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione, hurry up and to see.
