Sulfuric acid magnesium salt (1:1) → HCID 178521076, compound

Participants

Reaction Steps

To a stirred solution of (S)-(+)-2-amino-2-phenylethanol (271 mmol, 37.2 g) in methylene chloride (350 mL) was added 2-bromobenzaldehyde (271 mmol, 31.8 mL, 50.2 g) and anhydrous magnesium sulfate (50 g). The mixture stirred 3 h at room temperature then left to stand overnight. Filtered through dicalite and evaporated to dryness to give a pale yellow solid. This solid was stirred in dry ether (100 mL) for 30 min, then filtered, washed with ether, and dried in vacuo to give (S,E)-2-(2-bromobenzylideneamino)-2-phenylethanol (65.1 g) as a colourless solid.
