Adding a certain compound to certain chemical reactions, such as: 68282-53-1, name is 5-Methyl-1H-imidazole-4-carbaldehyde, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 68282-53-1, SDS of cas: 68282-53-1
COMPOUND 12.1. 19: 4-f6, {6s7-DIMETHOXY-2-r (4-METHYL-lH-IMIDAZOL-5- YL)METHYL]-1,2,3,4-TETRAHYDROISOQUINOLIN-1-YL}-N,N- DIETHYLBENZAMIDE; INTERMEDIATE 5.1. 7 (50 mg, 0.14 mmol) and 4-methyl-5-imidazolecarbaldehyde (30 mg, 0.27 mmol) were dissolved in DCE (3.0 mL). After stirring for 10 min at room temperature, sodium triacetoxyborohydride (86 mg, 0.41 mmol) was added and the mixture was stirred for 18 h at room temperature. DCM and 1 M sodium hydroxide solution were added and the mixture was passed through a Whatman 1PS silicon-treated filter paper. The organic phase was evaporated and the crude product was purified by flash chromatography to yield the product (57 mg, 0.12 mmol, 91%). 1H NMR (500 MHz, CDC13): 1. 08, 1.22 (2 brs, 6H), 2.07 (s, 3H), 2.54, 2.72, 2.90, 3.06 (4 m, 4H), 3.25, 3.54 (2 brs, 4H), 3.39, 3.59 (2 d, J 13 Hz, 2H), 4.56 (s, 1H), 6.16, 6.59 (2 s, 2H), 7.29 (s, 4H), 8.38 (brs, lH). l3C NMR (125 MHz, CDC13) : 11.14, 13.43, 14.03, 28.07, 39.69, 43.67, 46.67, 49. 48, 56.04, 56.06, 67.48, 111.2, 112.0, 126.5, 129.9, 127.2, 127.3, 129.3, 130.2, 136.1, 133. 3, 145.9, 147.6, 147.7, 171. 8. (+) LRESIMS mlz 369 (100), 463 (35).
