Nitromethane → HCID 86729779, compound

Participants

Reaction Steps

The compound obtained in Step 1 (21.69 g, 98.31 mmol), DBU (16.30 mL, 108.14 mmol) and nitromethane (6.00 g, 98.31 mmol) were stirred at room temperature for 14 hr. To the reaction solution was added brine at room temperature, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 5 to 30% ethyl acetate/hexane) to give N-(3-chloro-4-cyanophenyl)-3-methyl-4-nitrobutanamide (21.20 g, 75 mmol, 77%) as a pale-orange powder.
