4-methyl-4-nitropentanenitrile

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4-Methyl-4-nitrovaleronitrile (10.4 g, 13 mmol) was dissolved in methylene chloride (100 ml) and 1M diisobutyl aluminum hydride-hexane solution (100 ml) was added dropwise at −50° C. The mixture was stirred for 0.5 h, and water (8 ml) was added gradually, after which magnesium sulfate (5.0 g) was added. The mixture was filtrated and 1N hydrochloric acid (50 ml) was added. The mixture was stirred for 0.5 h and the layers were separated. The organic layer was washed with saturated brine and the solvent was evaporated. The residue was dried to give oily 4-methyl-4-nitropentanal (6.9 g, 48 mmol). The mixture was filtrated 1N hydrochloric acid (50 ml) was added The mixture was stirred for 0.5 h the layers were separated The organic layer was washed with saturated brine the solvent was evaporated The residue was dried

Procedure: Acrylonitrile (6.0 g, 113 mmol), 2-nitropropane (12.0 g, 135 mmol) and hexadecyltrimethyl ammonium chloride (2.0 g) were stirred in a 0.1N aqueous sodium hydroxide solution (200 ml) overnight at room temperature. The layers were separated and the aqueous layer was extracted twice with methylene chloride (50 ml). The combined organic layer was washed with saturated brine (30 ml). The solvent was evaporated and the residue was dried to give oily 4-methyl-4-nitrovaleronitrile (10.4 g, 73 mmol, yield 64.6%). The layers were separated the aqueous layer was extracted twice with methylene chloride (50 ml) The combined organic layer was washed with saturated brine (30 ml) The solvent was evaporated the residue was dried

Procedure: (vii-1) Acrylonitrile and 2-nitropropane are reacted in the presence of hexadecyltrimethyl ammonium chloride in an aqueous alkali solvent such as aqueous sodium hydroxide solution and the like. Then, the reaction mixture is extracted to give 4-methyl-4-nitrovaleronitrile (European Journal of Organic Chemistry (1998), (2), 355–357). The obtained 4-methyl-4-nitrovaleronitrile can be isolated and/or purified by a conventional method, such as crystallization, chromatography and the like, but generally, can be used in the next step without isolation and/or purification. Then, the reaction mixture is extracted
