To the above phenoxyacetonitrile (7.21 g, 35.2 mmol) in 60 ml of THF at 8° is added 1M diborane (61.50 g, 61.5 mmol) over 45 min. The reaction is warmed to RT and stirred for 6 hours. The reaction is stirred for 16 hours. The THF-H2O is removed in vacuo and water and ether are added to the white solid, followed by 10% aqueous sodium hydroxide to basify. The product is extracted with ether (3×) and the combined organic phases are washed with water and with brine, dried, filtered and solvent removed to give 2-[4-(1-methylpropoxy)phenoxy]ethylamine.
