Sodium triacetoxyborohydride → 6-Methoxy-8-{4-[2-(7-methoxy-1-benzofuran-3-yl)-1-methylethyl)piperazin-1-yl]quinoline

Participants

Reaction Steps

6-methoxy-8-{4-[2-(7-methoxy-1-benzofuran-3-yl)-1-methylethyl)piperazin-1-yl]quinoline was prepared by generally following the procedure outlined in example 35, step 2, starting from the 1-(7-methoxy-1-benzofuran-3-yl)acetone (204 mg, 1 mmol) and 6-methoxy-8-piperazino quinoline (243.0 mg, 1 mmol) in 1,2-dichloroethane (100 ml) and acetic acid (1 ml), sodium triacetoxyborohydride (422 mg, 2 mmol). The product was purified by silica-gel column chromatography by eluting it initially with 80% ethyl acetate:hexane and then with 5% methanol:ethyl acetate, yielding a brown semi-solid. Yield: 75 mg (17%); (M+H): 432.
