Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 51388-20-6, name is 4-(Benzyloxy)aniline hydrochloride, A new synthetic method of this compound is introduced below., HPLC of Formula: C13H14ClNO
Example 52-1 NL- (4-benzyloxyphenyl)-4-methoxybenzamidine To a solutionof 4-benzyloxyaniline hydrochloride (3g) in tetrahydrofuran (15ML), 1.OM sodium bis (trimethylsilyl) amide in tetrahydrofuran (26. 7ML) wasadded dropwise at room temperature. After the mixture was stirred for20min, anisonitrile (1.69g) was added.The reaction mixture was stirred for 4hrs, and then poured into 300ML OFice-water. The precipitates were collected by filtration, washed withdiisopropyl ether to give the target compound (3.3g).1H NMR (200MHZ, DMSO-D6, D) : 3.8 (3H, s), 5.05 (2H, s), 6.09 (2H, bs),6.74-6. 8 (2H, m), 6.96 (4H, d, J=8.5Hz), 7.29-7. 49 (5H, m), 7.92 (2H,d, J=8.9Hz).MS m/e: 333 (M+H) +.
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.
