Reaction Conditions:
with hydrogenchloride in water;ethyl acetate at 20; for 0.25 h;
Steps:
4 Example 4: Preparation of 1 -(2-nitrophenyl)piperazine hydrochloride (llla.HCI)
To a solution Ilia (13.2 g, 63.7 mmol) in EtOAc (100 mL) at room temperature 37% HCI (5 mL) was added. Obtained mixture was stirred at room temperature for 15 min, then precipitate was filtered off, washed with EtOAc (2 x 20 mL) and dried to afford 1 -(2-nitrophenyl)piperazine hydrochloride llla.HCI as yellow powder (13.8 g, 86% yield): H NMR (DMSO-c 5, 500 MHz) δ 3.15 (m, 4H), 3.24 (m, 4H), 7.22 (m, 1 H), 7.39 (m, 1 H), 7.64 (m, 1 H), 7.88 (dd, J = 1.5, 8.1 Hz, 1 H), 9.57 (br s, 2H).
