Reaction Steps

To a solution of diphytanyl methanol (6.4 g, 10.3 mmol) and 4-(dimethylamino) butyric acid hydrochloride (2.25 g, 13.4 mmol) in anhydrous dichloromethane (60 mL) under nitrogen at room temperature was added EDC (2.77 g, 18.0 mmol), diisopropylethylamine (5.4 mL, 31.0 mmol), and 4-dimethylaminopyridine (45 mg, 0.37 mmol). After 16 hours the reaction mixture was diluted with dichloromethane (75 mL). The organic layer was washed with saturated NaHCO3, water, and brine, and then dried on MgSO4, filtered, and concentrated. The resulting yellow oil was purified by column chromatography (column 10″L×2″W; eluted with a gradient of 100% hexanes→10%→50% ethyl acetate in hexanes) to afford the product as a pale yellow oil (3.53 g, 49%) with recovery of some phytanyl methanol (2.81 g, 44%).
