The mixture was stirred overnight at room temperature, diluted with 600 mL EtOAc and filtered through a CELITE pad to remove insoluble materials. The solution washed with water, brine, dried over MgSO4, concentrated and purified by chromatography to provide 14.1 g of 3-(4-chloro-phenyl)-prop-2-ynylamine. MS: m/e 166.1 (MH+)
