122833-04-9, 2-Methoxy-4-(4-methylpiperazin-1-yl)aniline is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To Int-17 (50 mg, 0.148 mmol) and 2-methoxy-4- (4-methylpiperazin-l-yl) aniline (33 mg, 0.148 mmol) in MeOH (1 mL), 2 drops of 4 M HC1 (aq.) was added. The solution was irradiated under microwave conditions for 30 minutes at 160 C. The solution was transferred to a separatory funnel with EtOAc (40 mL), and washed with saturated NaHCCb (10 mL). The aqueous layer was re-extracted with EtOAc (2 x 20 mL). The organic layers were combined, dried (Na2S04), filtered, and concentrated under reduced pressure. The resulting crude mixture was purified by flash chromatography (S1O2) eluting with DCM in MeOH (0% to 10%) to provide the title compound as a thin film (27 mg, 35%). HPLC: 94% [tR = 5.9 min, 45% MeOH, 55% water (with 0.1% TFA), 20 min]. NMR (400 MHz, DMSO-d6): delta 7.87 (d, / = 8.8 Hz, 1H), 7.85 (s, 1H), 7.40 (d, / = 8.1 Hz, 2H), 7.31 (t, / = 6.8 Hz, 1H), 7.29 (s, 1H, disappeared on D20 shake), 7.23 (t, / = 8.1 Hz, 1H), 6.60 (d, / = 2.5 Hz, 1H), 6.43 (dd, / = 8.8, 2.5 Hz, 1H), 3.82 (s, 3H), 3.59 (q, / = 6.8 Hz, 2H), 3.18 (d, / = 6.8 Hz, 3H from methanol), 3.10-3.04 (m, 4H), 2.46-2.41 (m, 4H), 2.20 (s, 3H). HPLC-MS (ESI+): m/z 523.2 [25%, (M35C135C137C1+H)+], 521.2 [25%, (M35C135C135C1+H)+], 262.2 [100%, (M35C135C137C1+2H)2+], 261.2 [95%, (M35C135C135C1+2H) 2+]. LC-MS (ESI+): 521.2 [100%, (M35C135C135C1+H)+]. HRMS (ESI+): m/z calcd for C24H27Cl3N60 (M+H)+ 521.1385, found 521.1390.
