Procedure

Step E (1): Methyl 3-(dipropylcarbamoyl)benzoate. To a solution of 3-(methoxycarbonyl)benzoic acid (6.7 g, 37.2 mmol) in DMF (60 mL) was added HATU (17.0 g, 44.7 mmol) and dipropylamine (9.4 g, 93 mmol) and the reaction mixture was stirred at rt overnight. Ethyl acetate (600 mL) was added and the mixture was washed with H2O, dried and concentrated to give the title compound was used in the next step without purification.

Workup

  1. washthe mixture was washed with H2O
  2. customdried
  3. concentrationconcentrated
