실험 절차

To a solution of 2-(isopropylamino)-6-nitrobenzonitrile (Example 90c) (0.21 g, 1.02 mmol) in MeOH (9 mL) was added concentrated HCl (2 mL). Then Fe (0.17 g, 3.07 mmol) was added portionwise, and the reaction mixture was refluxed at 90° C. for 15 minutes. After cooling to room temperature, dilution with H2O (50 mL) and extraction with DCM (3×50 mL), the combined organic phases were washed with brine, dried over MgSO4 and the solvents were evaporated to give 2-amino-6-(isopropylamino)benzonitrile (0.19 g, 100%) as a brown oil which was used in the next step without any further purification. MS 176 (MH+).
