Reaction Steps

5-amino-4-chloro-2-(4-oxobutyl)benzonitrile (544 mg, 2.443 mmol) was taken up in MeOH (6 mL) and THF (2.000 mL) and cooled to 0° C. NaBH4 (277 mg, 7.33 mmol) was added, and the reaction was stirred at 0° C. for 2 h (reaction followed by TLC until no SM detected). The reaction was quenched with water and extracted 2× with DCM. The organic layers were combined, dried over Na2SO4, filtered, and concentrated. The material was purified by flash column chromatography (0-50% EtOAc/DCM; 40 g column). 5-amino-4-chloro-2-(4-hydroxybutyl)benzonitrile (260 mg) was obtained as a yellow glass.
