Reaction Steps

To a stirred solution of aniline 12 (1.0 g, 6.1 mmol) in EtOH:H2O (9:1) was added 2-propylpentyl 4-methylbenzenesulfonate (0.87 g, 3.08 mmol). The reaction mixture was heated under reflux for 4 days, concentrated under reduced pressure. The residue was diluted with water and extracted with EtOAc three times. Combined organic layers were dried over anhydrous sodium sulfate and concentrated under reduced pressure to dryness. Purification by flash chromatography (25% EtOAc—hexanes) gave 3-hydroxy-3-(3-(2-propylpentylamino)phenyl)propanenitrile as a colorless semi-solid. Yield (0.3 g, 18%); 1H NMR (400 MHz, CDCl3) δ 7.17 (t, J=7.6 Hz, 1H), 6.66 (d, J=7.6 Hz, 1H), 6.62 (d, J=2.0 Hz, 1H), 6.57 (dd, J=2.0, 8.0 Hz, 1H), 4.95 (dt, J=3.2, 6.0 Hz, 1H), 3.72 (bs, 1H), 3.02 (d, J=6.0 Hz, 2H), 2.80 (d, J=6.8 Hz, 2H), 2.89 (d, J=3.2 Hz, 1H), 1.64-1.57 (m, 1H), 1.37-1.20 (m, 8H), 0.84 (t, J=6.8 Hz, 6H).
