1-Methylpiperazine → HCID 178480926, compound

Participants

Reaction Steps

A solution of trans-[4-(2-chloro-acetylamino)-cyclohexyl]-carbamic acid tert-butyl ester (330 mg, 1.14 mmol) in DCM (12 mL) was added to a solution of methylpiperazine (0.1 mL, 0.95 mmol) in DCM (1 mL) at RT. The resulting mixture was allowed to stir overnight, then diluted with DCM, and washed with a saturated aqueous solution of NaHCO3. The aqueous phase was extracted with DCM and then EtOAc. The combined organic phases were dried over Na2SO4, filtered and concentrated under reduced pressure to yield 199 mg of trans-{4-[2-(4-methyl-piperazin-1-yl)-acetylamino]-cyclohexyl}-carbamic acid tert-butyl ester without further purification.
