Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 766545-20-4, name is 2-Chloro-5,6,7,8-tetrahydro-1,6-naphthyridine hydrochloride, This compound has unique chemical properties. The synthetic route is as follows., category: chlorides-buliding-blocks
Following the procedure described in Example 12,Was reacted with 0.84 g (0.0075 mmol) of N-cyanoethyl ester from 1.03 g (0.005 mol) of 2-chloro-5,6,7,8-tetrahydro-1,6-naphthyridine hydrochloride,To give 0.8 g of a white solid, A mixture of 1.2 g (0.004 mol) of 2-chloro-4,5,6,7-tetrahydrothiazole [5,4-c] pyridine trifluoroacetate,0.67 g (0.006 mol)N-cyanoethyl esterWas added to a reaction flask equipped with 30 ml of methanol,0.73 g (0.0048 mol) of DBU was added,Heating to reflux reaction,After 2 hours the TLC monitoring reaction was complete,Cooling white solid precipitation,
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 766545-20-4.
