Application of 4584-46-7, The chemical industry reduces the impact on the environment during synthesis 4584-46-7, name is 2-Chloro-N,N-dimethylethanamine hydrochloride, I believe this compound will play a more active role in future production and life.
A solution of 5-nitroindoline (6) (0.5 g, 3.05 mmol) in DMF (10 mL) was treated with NaH (0.39 g, 9.75 mmol, 60% wt in mineral oil) at 0 C resulting in an orange mixture. ;The reaction mixture was then treated with 2-chloro-N,N-dimethylethanamine hydrochloride (0.87 g, 6.09 mmol) resulting in a dark red mixture. ;The reaction was heated to 90 C and stirred for 1.5 h. ;After allowing the reaction to cool to room temperature, water was added and the product was extracted into EtOAc. ;The combined ethyl acetate layer was washed with water, brine and dried (Na2SO4). ;Solvent was evaporated and the crude was purified by flash column chromatography (2 M NH3 in MeOH:CH2Cl2, 2.5:97.5) to obtain the title compound (0.4 g, 56%) as a solid. 1H NMR (DMSO-d6) delta 7.96 (dd, 1H, J = 2.1, 8.7 Hz), 7.79 (d, 1H, J = 2.1 Hz), 6.49 (d, 1H, J = 9.0 Hz), 3.72 (t, 2H, J = 8.7 Hz), 3.39 (t, 2H, J = 6.6 Hz), 3.04 (t, 2H, J = 8.7 Hz), 2.44 (t, 2H, J = 6.3 Hz), 2.18 (s, 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-Chloro-N,N-dimethylethanamine hydrochloride, other downstream synthetic routes, hurry up and to see.
