16154-72-6, 3-Chloro-4-(4-methylpiperazin-1-yl)benzenamine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To obtain the title compound of Example 31 , 5-(2-chloro-4-pyrimidinyl)-lambda/-ethyl-4-[3- methyl-5-(methyloxy)phenyl]-1 ,3-thiazol-2-amine (0.066 g, 0.183 mmol), prepared by a procedure analogous to Example 25, Step F, and [3-chloro-4-(4-methyl-1- piperazinyl)phenyl]amine (0.041 g, 0.183 mmol) were combined with iPrOH (2 ml.) and concentrated HCI (2 drops) in a microwave vial. The reaction was heated to 18O0C for 20 min in the microwave then cooled to rt. TEA (approx. 0.1 ml.) and silica gel were combined with the reaction and the resulting mixture was concentrated to dryness and subsequently adhered to silica gel. Column chromatography using EtOAc, MeOH, and NH4OH yielded fractions which were concentrated to dryness. This material was then further purified on a reverse phase acidic HPLC. The resulting fractions were free-based via extraction and concentrated to dryness to yield 35 mg of the title compound of Example 31 (35%Y). 1H NMR (400 MHz,DMSO-d6) delta 9.51 (s, 1 H), 8.25 (t, J = 5.4 Hz, 1 H), 8.07 (d, J = 5.6 Hz, 1 H), 8.03 (d, J = 2.5 Hz, 1 H), 7.54 (dd, J = 8.8, 2.6 Hz, 1 H), 7.06 (d, J = 8.9 Hz, 1 H), 6.88 (s, 1 H), 6.82 (d, J = 9.7 Hz, 2 H), 6.29 (d, J = 5.5 Hz, 1 H), 3.72 (s, 3 H), 3.28 (m, 2 H), 2.91 (br, 4 H), 2.48 (m, 4 H), 2.30 (s, 3 H), 2.23 (s, 3 H), 1.19 (t, J = 7.0 Hz, 3 H). HRMS C28H33N7OSCI (M+H)+ calcd 550.2156, found 550.2167.
16154-72-6, The synthetic route of 16154-72-6 has been constantly updated, and we look forward to future research findings.
