Reaction Steps

Concentrated hydrochloric acid (6.0 mL) was added to a solution of 4-tert-butyl 1-isopropyl 2-methylpiperazine-1,4-dicarboxylate (4.2 g, 14.6 mmol) in methanol (250 mL) and allowed to stir at ambient temperature under N2 blanket for 3d. The solution was then evaporated to dryness and the resultant viscous yellow oil triturated in acetone to precipitate a fine white powder which was isolated by filtration, under N2 blanket, to afford 2.0 g. LRMS (ESI) m/z 187.0 [(M+H)]+, calc'd for C9H18N2O2: 186.26.
