Participants

Reaction Steps

The acid chloride from step 1 was taken up in DCM (2 mL) and added drop-wise to a mixture of 1,1-dimethylethyl (2S)-2-methyl-4-{[4-(methylamino)phenyl]methyl}-1-piperazinecarboxylate (D3) (0.170 g, 0.53 mmol) and triethylamine (0.11 mL) in DCM (2 mL). The reaction mixture was stirred at room temperature under argon overnight then diluted with water (20 mL) and DCM (20 mL). The aqueous layer was extracted with DCM (20 mL) and the combined organic layers were dried, concentrated and purified by column chromatography. Elution with 0-30% EtOAc/pentane gave the title compound as a colourless oil (0.244 g). MS (ES): MH+ 596.2.
