Reaction Steps

Step 2 A solution of 5-(2-fluorophenyl)-3-hydroxy-2,3,4,9-tetrahydro-1H-carbazole-8-carboxylic acid (0.069 g, 0.213 mmol) in DMF (1.07 mL) was treated with ammonium chloride (0.023 g, 0.427 mmol), HOAT (0.058 g, 0.427 mmol), EDC (0.082 g, 0.427 mmol) and DIEA (0.149 mL, 0.853 mmol) and stirred over a weekend. The mixture was diluted with DCM, washed with 5% hydrochloric acid, NaHCO3 (aq), brine and 10% aqueous lithium chloride, dried and concentrated to give 5-(2-fluorophenyl)-3-hydroxy-2,3,4,9-tetrahydro-1H-carbazole-8-carboxamide as a light yellow foam (0.045 g, 65%). Mass spectrum m/z 325.1 (M+H)+.
