Adding a certain compound to certain chemical reactions, such as: 13330-96-6, 4-(Dimethylamino)butan-1-ol, 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, 13330-96-6, blongs to alcohols-buliding-blocks compound. Formula: C6H15NO
General procedure: To a solution of 6-substituted pyridazinone 9 (0.5 mmol) in DMF (10 mL) was added Cs2CO3 (0.55 mmol). An appropriately substituted nitro benzyl chloride (0.52 mmol) was added and the resulting mixture was stirred at 40-50 C for 3 h, the solvent was removed under reduced pressure and the residue was dissolved in EtOAc (30 mL), which was then washed with brine (3 × 10 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo. The crude product, 2-nitrobenzyl-6-substituted-pyridazin-3(2H)-one (10), was used in the next step without further purification. To a solution of 10 in 95 % ethanol (50 mL) was added acetic acid (10 mmol) followed by slow addition of iron powder (2 mmol). The resulting mixture was stirred for 5 h at 100 C. The mixture was then filtered through celite and the filter cake was washed with 95 % ethanol (3 × 15 mL). The combined ethanol filtrates were evaporated in vacuo and the residue was re-dissolved in ethyl acetate (30 mL). The organic layer was washed with brine (3 × 10 mL) and 2 M NaOH (10 mL) sequentially. The organic layer was dried over anhydrous Na2SO4, evaporated in vacuo to afford 2-aminobenzyl-6-substituted-pyridazin-3(2H)-one (11) as a yellow solid, which was used without further purification. To a stirred solution of 11 and triphosgene (1 mmol) in dry dichloromethane (5 mL) was added triethylamine (2 mmol) under nitrogen atmosphere. A solution of the corresponding alcohol (1 mmol) in dichloromethane (5 mL) was added 5-10 min later and the mixture was stirred at room temperature overnight, diluted with dichloromethane (15 mL) and washed with water (3 × 20 mL). The organic phases were separated, combined, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by using column chromatography to afford the corresponding product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,13330-96-6, its application will become more common.
