Sodium Hydroxide → HCID 22407754, compound

Participants

Reaction Steps

A solution of 41.3 g (400 mmol) of 3-dimethylaminopropanol in 200 ml of methylene chloride was added to a solution of 107.3 g (400 mmol) of 3,5-di-tert-butyl-4-hydroxybenzoyl chloride prepared as described in Example 1 in 400 ml of methylene chloride over a period of seven minutes. The reaction was exothermic. The reaction mixture was stirred for 90 minutes at room temperature and then washed with a solution of 16.0 g (400 mmol) of NaOH in 600 ml of water and then with water. The solution was dried over magnesium sulfate and concentrated to a residue on a rotary evaporator. The residue was then heated to reflux in 800 ml of heptane and filtered through supercel. The filtrate was cooled and the white solid was collected, washed with heptane and dried to give 92.3 g (68.8% of theory) of 3-dimethylaminopropyl 3,5-di-tert-butyl-4-hydroxybenzoate.
