White solid | [Uses]
(R)-4-Boc-2-methylpiperazine is a reagent used in organic synthesis. Used in the synthesis of orally bioavailable inhibitors of 11-β-hydroxysteroid | [Synthesis]
To a solution of (R)-methylpiperazine (400 mg) in dichloromethane (20 mL) at 0 ℃ was added di-tert-butyl dicarbonate (871 mg). The reaction was stirred at room temperature for 4 h and then quenched with water (20 mL), followed by extraction into dichloromethane (2 x 40 mL). The combined organics were washed with saturated aqueous brine solution (40 mL), dried (MgSO4), and concentrated to give (R)-1-Boc-3-methylpiperazine as a white solid (669 mg, 84%).
