Morpholine → HCID 66878419, compound

Participants

Reaction Steps

Morpholine (250 mg, 2.87 mmol) was added to a suspension of 6-[4-(4-nitrophenyl)piperazin-1-yl]pyridine-3-carbaldehyde (750 mg, 2.41 mmol) and sodium cyanoborohydride (454 mg, 7.23 mmol) in a mixture of tetrahydrofuran (10 mL) and acetic acid (0.5 mL) at ambient temperature then heated at reflux for 3 h. The mixture was then concentrated in vacuo to give a gummy solid which was dissolved in chloroform (40 mL), washed with water (2×20 mL), brine (2×15 mL), dried over anhydrous sodium sulfate and concentrated in vacuo to give the crude compound. Purification by column chromatography over neutral alumina using 20-30% of ethyl acetate in petroleum ether afforded 4-[[6-[4-(4-nitrophenyl)piperazin-1-yl]-3-pyridyl]methyl]morpholine (550 mg, 59%).
