A solution of 16.7 grams of 3,5-di-tert.butyl-4-hydroxybenzylpyridinium chloride in 50 milliliters of ethanol was added dropwise in 15 minutes to a slurry of 2.0 grams of sodium hydroxide and 13.4 grams of 1-nitropropane (200% excess) in 50 milliliters of ethanol. The reaction mixture as stirred for 3 hours and was then poured into 600 milliliters of water. The oil which precipitated was separated by extraction with hexane. The extract was evaporated to give 15.0 grams (98% of theory) of 1-ethyl-2-(3,5-di-tert.butyl-4-hydroxyphenyl)-1-nitroethane which melted at 55°-60° C.
