실험 절차

A mixture of 1-[3-(methyloxy)-4-nitrophenyl]piperazine (Example 135, step A) (0.50 g, 2.1 mmol) and 1-iodopropane (0.72 g, 4.22 mmol) was stirred in acetonitrile (42 mL) at rt under N2. To this mixture was added NaHCO3 (0.27 g, 2.5 mmol). The reaction was then heated to reflux and stirred for 24 h. The reaction was cooled to rt, concentrated under vacuum and the residue chromatographed on silica gel to give the title compound of step A (206 mg, 0.74 mmol, 35%) as a yellow oil. MS (ESI): 280 [M+H]+.
