실험 절차

A solution of trimethylaluminium (2M in toluene, 1.3 ml, 2.6 mmol) is added over a period of 5 min to a solution of 3-nitro-4-methyl-aniline (152 mg, 1.00 mmol) and 4-(4-methyl-piperazin-1-ylmethyl)-benzoic acid methyl ester (248 mg, 1.00 mmol) in toluene (3.0 ml) at 45° C. under an atmosphere of argon. After gas evolution ceases, the dark brown reaction mixture is stirred 30 min before being cooled to 0° C. An aqueous saturated solution of potassium-sodium tartrate (20 ml), t-butyl methyl ether (15 ml) and methylene chloride (10 ml) are added sequentially. The organic phase is separated and washed with aqueous saturated NaHCO3 (10 ml) and aqueous saturated NaCl (10 ml). The aqueous phases are back-extracted with t-butyl methyl, ether (2×15 ml). The organic phases are combined, dried over MgSO4 and concentrated in vacuo to give 383 mg (96 area % by HPLC) of the title compound as pale yellow crystals.
