Reaction Steps
The acid chloride from step 1 was dissolved in DCM (15 mL) and added to a mixture of 1,1-dimethylethyl (2S)-2-methyl-4-{[4-(methylamino)phenyl]methyl}-1-piperazinecarboxylate (D3) (0.500 g, 1.57 mmol) and triethylamine (0.284 mL, 2.04 mmol) in DCM (15 mL). The reaction mixture was stirred at room temperature overnight and then washed with water (×2) and brine. The organic layer was dried and concentrated to give the crude product, which was purified by column chromatography. Elution with 20-60% EtOAc/pentane yielded the title compound as a yellow oil/solid (0.658 g). δH (CDCl3, 400 MHz) 7.56 (1H, m), 7.46 (1H, m), 7.17 (2H, m), 6.99 (2H, m), 4.16 (1H, br.s), 3.79 (1H, d), 3.50 (3H, s), 3.46 (1H, d), 3.32 (1H, d), 3.07 (1H, m), 2.69 (1H, d), 2.50 (1H, d), 2.08 (1H, m), 1.97 (1H, m), 1.46 (9H, s), 1.19 (3H, d). MS (ES): MH+ 459/461.
