Reaction Steps
This example illustrates a synthesis of 1-Octylamino-10-hydroxy-11-(N-methylacetamido)undecane (compound no. 77). Sodium hydride (0.56 g, 23 mmol) was added to a solution of 1-bromo-10-undecene (5.4 g, 23 mmol) and N-methylacetamide (91.7 g, 23 mmol) in DMSO (40 mL). After 8 hours, the reaction was complete and the mixture added to water (100 mL) and extracted with dichloromethane (3×100 mL). The combined extracts were washed with water (70 mL) and saturated aqueous salt solution (70 mL), and dried over sodium sulfate. The solvent was evaporated under vacuum to give a yellow residue, which was chromatographed (silica/ethyl acetate), yielding 2.95 g of 1-(N-methylacetamido)-10-undecene as a colorless oil (57% yield).
