Procedure

Into a three-necked flask (200 ml), a toluene solution (56 g) containing diethylamine (25.80 g; 0.352 moles) was placed. While the flask was cooled with ice water and the solution was stirred, a toluene solution (30 g) of 2-methoxybenzoyl chloride (2.00 g; 0.117 moles) was added dropwise over 30 minutes. After the addition was completed, water was added to the resultant mixture, and diethylamine and diethylamine hydrochloride in excess amounts were removed. The obtained toluene layer was dehydrated with MgSO4. Then, the solvent was removed by distillation, and a light yellow liquid was obtained (the obtained amount: 22.81 g; the yield: 94%).
