Application of 67346-74-1, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 67346-74-1 as follows.
Reference Example 1 3-(3-(4-Benzyloxy-benzyl)-isoxazol-5-yl)-pyridin-2-ylamine; To a mixture of 4-benzyloxy-phenyl-acetohydroximoyl chloride (1.2 g, 4.4 mmol) described in Manufacturing Example 1-1-3 and tetrahydrofuran (34 mL) were added 3-Ethynyl-pyridin-2-ylamine (260 mg, 2.2 mmol) described in Manufacturing Example 1-2-3 and triethylamine (3.0 mL, 22 mmol) at 0 C., which was stirred for 1 hour at room temperature. To the reaction mixture was added water at room temperature, which was then extracted with ethyl acetate-tetrahydrofuran (2:1). The organic layer was washed with saturated aqueous sodium chloride, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate_heptane=1:3) to obtain the title compound (240 mg, 15%).1H-NMR Spectrum (CDCl3) delta (ppm): 4.00 (2H, s), 5.05 (2H, s), 5.41 (2H, s), 6.24 (1H, s), 6.71 (1H, dd, J=4.9, 7.6 Hz), 6.93-6.97 (2H, m), 7.18-7.22 (2H, m), 7.31-7.44 (5H, m), 7.70 (1H, dd, J=1.7, 7.6 Hz), 8.13 (1H, dd, J=1.8, 4.9 Hz).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,67346-74-1, its application will become more common.
