2-Methoxyaniline → HCID 11000238, compound

Participants

Reaction Steps

In a 50 ml two-necked flask placed under an argon atmosphere, 1.5 g (7 mmol, 1.4 eq) of (Boc)2O is dissolved in 5 ml of anhydrous CH2Cl2. 61 mg (0.5 mol, 10% eq) of DMAP dissolved in 5 ml of anhydrous CH2Cl2 is added, then 0.56 ml (5 mmol) of 2-methoxyaniline is added dropwise. The mixture is stirred at room temperature for 20 min before adding 0.5 ml (7 mmol, 1.4 eq) of 2-bromoethanol diluted in 5 ml of anhydrous CH2Cl2. The reaction is allowed to progress for 30 min at room temperature then for approximately 20 hours under reflux of dichlormethane. Then, the medium is cooled and concentrated under vacuum. The resulting dark pink solid is purified by chromatography on a silica gel column (eluent CH2Cl2) to give 1.33 g of a colorless oil (yield: 95%).
