Application of 2734-70-5, The chemical industry reduces the impact on the environment during synthesis 2734-70-5, name is 2,6-Dimethoxyaniline, I believe this compound will play a more active role in future production and life.
To a solution of 2,6-dimethoxyaniline (500 g, 3.25 mol, 1 eq) in DCM (5.0 L) was added 2,6-lutidine (1.5 L, 13.0 mol, 4 eq). The reaction mixture was cooled to 0 C (internal temperature) and CSC12 (374 mL, 4.88 mol, 1.5 eq) was added dropwise. The reaction mixture was then stirred for 2 h. The solvent was evaporated under reduced pressure and the material thus obtained was purified by SiC column to provide the title compound, 2-isothiocyanato-l,3-dimethoxybenzene, Example 82.0 as a white solid (1.06g, 2.80 mol, 86%). LCMS (ESI pos. ion) m/z: (M+H)+ = 196. NMR (400 MHz, CDCI3) delta 7.16 (t, J= 8.48 Hz, 1H), 6.55 (d, J = 8.48 Hz, 2H), 3.90 (m, 6H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2,6-Dimethoxyaniline, other downstream synthetic routes, hurry up and to see.
