[Cl:1][C:2]1[CH:9]=[C:8]([Cl:10])[CH:7]=[C:6]([CH2:11][O:12][CH3:13])[C:3]=1[C:4]#[N:5].CO.[OH-].[Na+]>C1COCC1>[Cl:1][C:2]1[CH:9]=[C:8]([Cl:10])[CH:7]=[C:6]([CH2:11][O:12][CH3:13])[C:3]=1[CH2:4][NH2:5]A solution of BH3 (3.5 mL, 1M in THF) was added to a solution of 2,4-dichloro-6-(methoxymethyl)benzonitrile (0.88 mmol) in 3 mL THF. The reaction mixture was heated to 60° C. for 2 h. At 0° C., 3.5 mL MeOH was dropwise added and the mixture was stirred until gas evolution was finished. An aq. solution of 10% NaOH was added still under cooling. The solvent was removed under vacuo, the residue was diluted with water and extracted 3 times with EtOAc. The combined organic layers were dried over MgSO4 and concentrated in vacuo to give the desired product as orange oil.
