Reaction Steps

Methanolic hydrogen chloride (4M, 5 mL) was added to a stirred, cooled (0° C.) suspension of N-[2-(4-t-butoxycarbonylpiperazin-1-yl)phenylmethyl]acetamide (668 mg, 2 mmol) in methanol (2 mL) and the mixture was stirred at room temperature for 4 h. The solvent was evaporated under reduced pressure to give the title compound as a colorless foam (536 mg, 99%), δH (360 MHz, d6 -DMSO) 9.20 (2H, br s), 8.26 (1H, br t, J 5.8 Hz), 7.26 (2H, m), 7.12 (2H, m), 4.33 (2H, d, J 5.8 Hz), 3.22 (4H, m), 3.04 (4H, m), and 1.89 (3H, s). m/e (ES+) 234 (MH+).
