Acetyl chloride → HCID 72533160, compound

Participants

Reaction Steps

To a solution of the (3R,9aS or 9aR)-3-{[(1,1-dimethylethyl)(dimethyl)silyl]methyl}octahydro-2H-pyrazino[1,2-a]pyrazine (D86, 217 mg) in 9 mL of dichloromethane was added triethylamine (212 μL) and it was brought to −10° C. A solution of acetyl chloride (54 μL) in 2 mL of dichloromethane was added dropwise. After 15 min the reaction was quenched by addition of MeOH. The crude was purified by flash chromatography (silica, CH2Cl2 to CH2Cl2: (0.5 M NH3 in MeOH) 95:5). The sample thus obtained was dissolved in CH2Cl2 and extracted with sat. NaHCO3. The organics were dried and the solvent removed, leading to the title compound (128 mg).
