Reference of 93919-56-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
6-Methoxy-5-({[4-(trifluoromethoxy)benzyl]amino}methyl)-2-naphthoic acid methyl ester To a stirred solution of 6-methoxy-5-formyl-2-naphthoic acid methyl ester (1.09 g, 4.46 mmol) in EtOH (40 ML) at room temperature was added 4-trifluoromethoxy-benzyl amine (0.749 ML, 4.91 mmol) followed by HOAc (0.255 ML, 4.46 mmol).After 10 min. at this temperature, sodium cyanoborohydride (0.420 g, 6.69 mmol) was added, and reaction was continued stirring at rt for 4 h.After 1 h at this temperature, the reaction was heated to 45 C. for 2 h.The solution was quenched with sat. aq. NaHCO3 (20 ML) and then extracted with EtOAc (200 ML).The organic layer was washed with brine (20 ML) and dried (MgSO4).After concentration, the residue was purified by flash chromatography (0 to 10% MeOH:CHCl3 gradient) to afford the product (0.780 g, 42%) as a solid; 1H NMR (DMSO-d6) delta3.77 (s, 2H), 3.86 (s, 3H), 3.88 (s, 3H), 4.07 (s, 2H), 7.26 (d, J =8.0 Hz, 2H), 7.44 (d, J=8.6 Hz, 2H), 7.48 (d, J=9.2 Hz, 1H), 7.88 (dd, J=1.9, 8.9 Hz, 1H), 8.06 (d, J=5.2 Hz, 1H), 8.08 (d, J=5.3 Hz, 1H), 8.52 (d, J=1.7 Hz, 1H); mass spectrum [(+) El], m/z 420 (M+H)+.
The synthetic route of (4-(Trifluoromethoxy)phenyl)methanamine has been constantly updated, and we look forward to future research findings.
