1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 4-(1-(3-Amino-4-methylbenzoyl)piperidin-4-yl)benzonitrile

Participants

Reaction Steps

A solution of 3-amino-4-methylbenzoic acid (1.36 g, 9.0 mmol), (4-(piperidin-4-yl)benzonitrile HCl salt (compound 1.5, 2.0 g, 9.0 mmol), EDCI (1.89 g, 9.9 mmol), HOBT (1.66 g, 9.9 mmol, with 20% H2O) and DIEA (3.13 ml, 18.0 mmol) in DMF (50 ml) was stirred at room temperature overnight. The reaction mixture was poured into cold water (300 ml) and off white solids precipitated. The precipitate was filtered, washed with water and dried under reduced pressure in an oven to yield 2.88 g (100%) of the title compound. m/z (ES+) 320 (M+H)+.
