Adding a certain compound to certain chemical reactions, such as: 631-58-3, name is Propanethioamide, belongs to amides-buliding-blocks 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 631-58-3, 631-58-3

N-[5-(2-Bromo-acetyl)-4-methyl-thiazol-2-yl]-acetamide (71.6 mg) (prepared by the procedure of WO 2005/068444) is dissolved in CH3OH (5 mL) at RT, followed by addition of thiopropionamide (21.4 mg) and ammonium phosphomolybdate¡ÁH2O (37.5 mg). After completion of the reaction, water is added (25 mL) and the precipitate is filtered off to obtain the title compound as a dark green powder. Title compound: HPLC (Method F) RT 4.86 minutes; MS (Method D) M+H 268.2 and M-H 266.2.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Propanethioamide, other downstream synthetic routes, hurry up and to see.

Here is a downstream synthesis route of the compound 631-58-3, 631-58-3

Reference Example L 26 2-ethyl-5-(2-fluoro-4-pyridyl)-4-(3-methylphenyl)-1,3-thiazole A solution of 2-bromo-2-(2-fluoro-4-pyridyl)-1-(3-methylphenyl)ethanone hydrobromide (11 g, 29 mmol) and thiopropionamide (2.7 g, 30 mmol) in N,N-dimethylformamide (30 mL) was stirred at room temperature for 14 hrs. Aqueous sodium hydrogen carbonate solution was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water, dried and the solvent was evaporated. The residue was purified by silica gel column chromatography (hexane-ethyl acetate = 4: 1) to give the title compound (3.3 g, yield 38%). oil 1H-NMR(CDCl3)delta: 1.64 (3H, t, J= 7.6Hz), 2.34 (3H, s), 3.10 (2H, q, J= 7.6Hz), 6.84-6.86 (1H, m), 7.05-7.09 (1H, m), 7.13-7.25 (3H, m), 7.37 (1H, s), 8.10 (1H, d, J= 5.6Hz).
