100% | With potassium carbonate; In water; acetone; | EXAMPLE 3 Preparation of Fmoc-1-amino-4-(4-ethoxyphenyl)cyclohexane-1-carboxylic acid (Fmoc-4-EtOApc-OH) A solution of 4-(4-hydroxyphenyl)cyclohexanone (5.0 g, 26.3 mmol) in acetone (100 mL) was treated with K2CO3 (14.5 g, 105 mmol, 4 equiv) and iodoethane (10.5 mL, 20.5 g, 131 mmol, 5 equiv.). The reaction was heated at 6520C. overnight. After the solvent was removed, the residue was treated with H2O and extracted with EtOAc. The organic extracts were combined and washed with brine, dried over Na2SO4 and concentrated in vacuum to give the spectroscopically pure 4-(4-ethoxyphenyl)cyclohexanone (5.74 g, 100%). 1H NMR (CDCl3) 7.15 (dt, 2H), 6.86 (dt, 2H), 4.02 (q, 2H), 2.99 (tt, 1H), 2.46-2.54 (m, 4H), 2.16-2.24 (m, 2H), 1.83-2.00 (m, 2H) and 1.41 (t, 3H); MS (electrospray) m/e, 219 (M+1)+, Calcd for C14H18O2, 218. |
