The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 14294-11-2, name is 1-(Pyridin-2-yl)thiourea. This compound has unique chemical properties. The synthetic route is as follows. Product Details of 14294-11-2
According to Scheme 3 Step 4: A solution of 2-bromo-1-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)propan-1-one (23.8 mmol, 7.70 g) and of 1-(pyridin-2-yl)thiourea (26.2 mmol, 4.02 g) in EtOH (200 mL) was stirred under reflux overnight. The reaction was quenched with water (200 mL) and the aqueous phase was extracted with DCM. The organic phase was dried over MgSO4, was filtered and was concentrated to yield a brown solid. The resulting crude product was purified by flash chromatography over silica gel using DCM/AcOEt (98:2) as eluent to yield after evaporation 4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-5-methyl-N-(pyridin-2-yl)thiazol-2-amine (20.7 mmol, 7.80 g, 87%) as a beige solid.LC (Zorbax SB-C18, 3.5 mum, 4.6×50 mm Column): RT=2.29 min; MS m/z ES+=378.
With the rapid development of chemical substances, we look forward to future research findings about 14294-11-2.
