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. 67952-93-6, name is 3-Chloro-4-methylbenzylamine, A new synthetic method of this compound is introduced below., Safety of 3-Chloro-4-methylbenzylamine
To a solution of (,S)-3-(5-(aminomethyl)-l-oxoisoindolin-2-yl)azepane- 2,7-dione (TFA salt) (68 mg, 0.176 mmol) in DMF (4 mL) was added CDI (29.0 mg, 0.18 mmol) and the suspension was stirred at RT for 14 h. Then (3-chloro-4-methylphenyl) methanamine (28.0 mg, 0.18 mmol) was added and the mixture was stirred at RT for 8 h. The suspension was diluted with water and extracted with DCM. The combined organic layers were dried over sodium sulfate, filtered and concentrated to give the crude product, which was purified by silica gel chromatography eluting with MeOH/DCM from 0% to 10% to give Compound 18 (21.0 mg, 25.1%) as a white solid. MS (ESI) m/z 469 A [M+H] +. MR (400 MHz, DMSO-de) delta 10.69 (s, 1H), 7.66 (d, J=8 Hz , 1H), 7.46 (s, 1H), 7.38 (d, J=8 Hz, 1H), 7.28 (d, J=7.2 Hz, 2H), 7.11 (d, J=8.8 Hz, 1H), 6.64-6.55 (m, 2H), 5.25-5.21 (m, 1H), 4.49 (s, 2H), 4.34 (d, 7 =6 Hz, 2H), 4.19 (d, 7 =6 Hz, 2H), 3.12-3.04 (m, 1H), 2.57 (d, 7 =16.8 Hz, 1H), 2.28-2.23 (m, 1H), 2.29 (s, 3H), 2.12-1.99 (m, 2H), 1.84-1.81 (m, 1H).
The synthetic route of 67952-93-6 has been constantly updated, and we look forward to future research findings.
