Synthetic Route of 60789-54-0, A common heterocyclic compound, 60789-54-0, name is ((4-Bromobutoxy)methyl)benzene, molecular formula is C11H15BrO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Example 115 4-Amino-5-chloro-2-methoxy-N-(piperidin-4-ylmethyl)benzamide dihydrochloride (1.1 g) as starting compound, potassium carbonate (1.5 g) and 4-benzyloxybutyl bromide (1.0 g) were reacted and treated in the same manner as in Example 52 to give 0.32 g of 4-amino-5-chloro-2-methoxy-N-((1-(4-benzyloxybutyl)piperidin-4-yl)methyl)benzamide. 1H-NMR (CDCl3,ppm)delta:1.40-1.81(9H,m), 2.82(2H,t), 2.98(2H,t), 3.20(2H,t), 3.44(4H,m), 3.82(3H,s), 4.45(3H,s), 5.93(2H,s), 6.48(1H,s), 7.33-7.45(5H,m), 7.66(1H,s), 8.00(1H,t)
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
