Participants

Reaction Steps

10.0 g (0.035 mol) of 1-(4-fluorophenyl)-2-dimethylamino-2-benzyl-propan-1-one and 18.4 g (0.25 mol) of 3-amino-1-propanol are dissolved in 20 ml of dry dimethylacetamide, and the solution is heated up to 150° C. together with 9.7 g (0.07 mol) of potassium carbonate, and stirred overnight (about 12 hours). After the solution is cooled down, it is poured into 300 ml of water and extracted with toluene. The organic phase is washed with water and saturated sodium chloride solution, and dried over MgSO4. After distilling off the toluene, the residue is purified by means of column chromatography on silica gel with ethyl acetate-hexane (1:1) as an eluent, and an oily product is obtained. The structure is confirmed by the 1H-NMR spectrum (CDCl3): δ [ppm]:1.14 (s, 3H), 1.50 (br, 1H), 1.93 (m, 2H), 2.33 (s, 6H), 2.96 (d, 1H), 3.37 (m, 2H), 3.42 (d, 1H), 3.85 (m, 2H), 4.45 (br, 1H), 6.56 (d, 2H), 6.89-6.91 (m, 2H), 7.10-7.12 (m, 3H), 8.45 (d, 2H).
