Electric Literature of 24016-03-3, 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 24016-03-3, name is 2-Amino-3-benzyloxypyridine. This compound has unique chemical properties. The synthetic route is as follows.
Example 1A Ethyl 8-(benzyloxy)-2-methylimidazo[1,2-a]pyridine-3-carboxylate 25 g (124.8 mmol) of 2-amino-3-benzyloxypyridine were dissolved in 781 ml of ethanol, 102.7 g (624.2 mmol) of ethyl 2-chloroacetoacetate and two tablespoons of 4 A molecular sieve were added, and the reaction mixture was then heated at reflux (bath temperature 100 C.) for 2 days. The mixture was concentrated, and excess ethyl 2-chloroacetoacetate was removed on a rotary evaporator with dry ice cooling. The residue was purified by silica gel chromatography (mobile phase cyclohexane:ethyl acetate gradient 9:1, 4:1). This gave 20.81 g of the target compound (54% of theory, purity 99%). LC-MS (Method 2): Rt=1.12 min MS (ESpos): m/z=311 (M+H)+ 1H NMR (400 MHz, DMSO-d6): delta=1.35 (t, 3H), 2.59 (s, 3H), 4.34 (q, 2H), 5.32 (s, 2H), 7.01-7.09 (m, 2H), 7.33-7.48 (m, 3H), 7.52 (d, 2H), 8.81-8.86 (m, 1H).
According to the analysis of related databases, 24016-03-3, the application of this compound in the production field has become more and more popular.
