Diisopropylethylamine → HCID 86599513, compound

Participants

Reaction Steps

To a solution of N,N-bis[4-(trifluoromethyl)benzyl]amine (0.733 g, 2.20 mmol) and {4-[(2S)-2,3-diethoxy-3-oxopropyl]phenoxy}acetic acid (0.593 g, 2.00 mmol) in methylene chloride (20 mL) were added N,N-diisopropylethylamine (0.80 mL, 4.6 mmol) and O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (0.674 g, 2.10 mmol) and the reaction mixture was stirred at room temperature for 4 h. The resulting solution was diluted with methylene chloride (130 mL) and the organic phase was washed with 5% HCl (3×75 mL), saturated aqueous NaHCO3 (2×75 mL), and brine (75 mL), dried over Na2SO4, and concentrated in vacuo. Purification on a prepacked column of silica gel (Isolute® SPE Column, 70 g/150 mL) with methanol (0-1% gradient) in methylene chloride as the eluent yielded 0.91 g (74%) of a whitish oil.
