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 a solution of Int-12 (100 mg, 0.312 mmol) and 2-methoxy-4-(4-methylpiperazin-l-yl)aniline (75 mg, 0.343 mmol) in 2-methoxyethanol (2 mL) was added 4 M HC1 in dioxane (0.086 mL, 0.343 mmol). The solution was stirred and heated at 110 C for 14 h. Then, additional 2-methoxy-4-(4-methylpiperazin-l-yl)aniline (18 mg, 0.081 mmol) and 1 drop of 4 M HC1 (aq) were added and the mixture was further irradiated under microwave conditions for 15 minutes at 160 C. The solution was concentrated under reduced pressure and partitioned between saturated NaHCC and DCM (20 mL each). The aqueous layer was re-extracted with DCM (20 mL). The organic layers were combined, dried (Na2S04), filtered, and concentrated under reduced pressure. The resulting crude mixture was purified by flash chromatography (Si02) eluting with DCM in MeOH (0% to 10%) to provide the title compound as a brown foam (75 mg, 48%). HPLC: 98% [tR = 8.7 min, 45% MeOH, 55% water (with 0.1% TFA), 20 min. lH NMR (400 MHz, DMSO-ifc): delta 7.87 (d, / = 8.8 Hz, 1H), 7.84 (s, 1H), 7.33-7.22 (m, 4H; 1H disappeared on D20 shake), 7.19-7.11 (m, 1H), 6.60 (d, J = 2.5 Hz, 1H), 6.42 (dd, / = 8.8, 2.5 Hz, 1H), 3.81 (s, 3H), 3.58 (q, / = 6.6 Hz, 2H), 3.10-3.05 (m, 4H), 3.03 (t, J = 6.6 Hz, 2H), 2.46-2.42 (m, 4H), 2.21 (s, 3H). HPLC-MS (ESI+): m/z 507.2 [45%, (M35C137C1+H)+], 505.2 [50%, (M35C135C1+H)+], 254.2 [60%, (M35C137C1+2H)2+], 253.2 [100%, (M35C135C1+2H)2+]. LC-MS (ESI+): 505.2 [100%, (M35C135C1+H)]. HRMS (ESI+): m/z calcd for C24H27C12FN60S (M+H)+ 505.1680, found 505.1683.
