Tetrahydrofuran → HCID 68872252, compound

Participants

Reaction Steps

To a solution of 3-chlorosulfonylnitrobenzene (45) (2.21 g, 10 mmol) in tetrahydrofuran (100 mL) at 0° C. were added diisopropylethyl amine (1.93 mL, 15 mmol) followed by N-methyl-4-aminopiperidine (46) (1.36 g, 12 mmol) and then the reaction mixture was stirred at room temperature for 2 hours. The reaction was quenched with water (50 mL), stirred for 30 minutes and the tetrahydrofuran layer was separated. The organic solution was concentrated under reduced pressure. The resulting residue was taken in dichloromethane (200 mL), washed with aqueous solution of sodium bicarbonate (2×100 mL) and then brine. The organic layer was dried over anhydrous sodium sulfate and solvent was removed under reduced pressure to afford the desired product, 3-(N-4-methylpiperidin-1-yl)aminosulfonylnitrobenzene (47). LCMS: purity: 93%; MS (m/e): 300 (MH+).
