Commercially available 4-dimethylaminobenzonitrile 18i (2 g, 13.7 mmol) dissolved in 15 ml of ether was added dropwise at 0° C. to LiAlH4 (2 equiv., 1 g) suspended in diethyl ether (40 ml). The mixture was stirred at room temperature for 24 hours. The reaction was quenched by addition of water and filtrated and the salts were washed with ether. The organic phase was separated, anhydrified and evaporated giving 1.85 g of a pale yellow oil. Yield=90% 1HNMR (DMSO, 200 MHz) δ 1.60 (2H, bs), 2.84 (6H, s), 3.57 (2H, s), 6.67 (2H, d, J=8.8 Hz), 7.12 (2H, d, J=8.6 Hz)
