To (R)-1-Boc-2-methylpiperazine (200.0 mg, 0.999 mmol) and sodium triacetoxyborohydride (444.5 mg, 2.097 mmol) in DMF (5 mL) was added acetone (116 mg, 0.147 mL, 1.997 mmol) and acetic acid (90.0 mg, 86 μL, 1.498 mmol). The reaction mixture was heated at 60° C. for 1 h. The reaction mixture was diluted with water and extracted three times with diethyl ether. The combined organics were dried over sodium sulfate, filtered, concentrated, and used without further purification. LCMS-ESI+: calc'd for C13H27N2O2 (M+H+): 243.2; Found: 243.2 (M+H+).
