Reaction Steps

A mixture of 3-nitro-4-chloro-benzonitrile (20.4 g, 112.2 mmol), and 4-aminobutanol (10 g, 112 mmol) and K2CO3 (30.9 g, 224 mmol) in CH3CN (100 ml) was stirred at 23° C. for 12 h. Starting material remains by TLC analysis. Additional 4-aminobutanol (2 g, 22 mmol) was added and stirring continued for 24 h. The mixture is filtered and concentrated. The residue is dissolved in EtOAc and washed with water. The extracts are dried over MgSO4 and concentrated to give 26 g (99%) of 4-(4-cyano-2-nitro-phenylamino)-butan-1-ol as an orange solid.
