Adding a certain compound to certain chemical reactions, such as: 4463-59-6, name is 1-(2-Bromoethoxy)-2-methoxybenzene, belongs to ethers-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 4463-59-6, Recommanded Product: 1-(2-Bromoethoxy)-2-methoxybenzene
EXAMPLE 68 1-[2-(2-Methoxyphenoxy)ethyl]-4-benzamidopiperidine 2-(2-Methoxyphenoxy)ethyl bromide (2.31 g.), 4-benzamidopiperidine (2.04 g.) and anhydrous potassium carbonate (1.38 g.) were well mixed and heated on a steam bath for 4 hr. The resultng mass was crushed and stirred in water (200 ml.) at 60 for 12 hr. Filtration afforded the crude base of the title compound (2.95 g.). Conversion to the hydrochloride by solution in ethanol/HCl and precipitation with ether provided 3.01 g. of the title compound, as the hydrochloride m.p. 193.4. Analysis: Found: C, 64.74; H, 7.08; N, 7.14. C21 H26 N2 O3.HCl requires C, 64.52; H, 6.96; N, 7.17%.
