1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 3-chloro-4-methyl-N-(1-methyl-1-phenylethyl)benzamide

Participants

Reaction Steps

In a similar manner to Step 1 of Example 137, 3-chloro-4-methylbenzoic acid (1.00 g, 5.86 mmol) was dissolved in DMF (20 mL), and the solution was treated with EDCI (2.25 g, 11.7 mmol), HOBT monohydrate (792 mg, 5.86 mmol) and cumylamine (1.69 mL, 11.7 mmol). The reaction mixture was added with water. The precipitated solid was collected by filtration and washed with water, followed by drying under reduced pressure. The obtained solid was purified by slurry using diisopropylether to obtain 3-chloro-4-methyl-N-(1-methyl-1-phenylethyl)benzamide (1.64 g, yield 97%).
