Participants

Reaction Steps

To a stirred solution of 3-(1-admantyl)-4-isopropoxybenzaldehyde (0.24 g, 0.8 mmol) in CH3NO2 (5 mL) was added CH3CO2NH4 (0.125 g, 1.6 mmol) and the mixture was stirred for 3 h at reflux. The solvent was evaporated to dryness and the residue was diluted to 50 ml with EtOAc and washed with 1M HCl and H2O. The organic layer was separated, dried over MgSO4 and filtered. The filtrate was evaporated to dryness to give the title product (0.275 g; 88%) as yellow solid. 1H-NMR (CDCl3) 1.41 (d, 6H, J=6 Hz); 1.7-1.76 (m, 6H); 2.08-2.12 (m, 9H); 4.68-4.74 (m, 1H); 6.85 (d, 1H, J=8.45 Hz); 7.33-7.38 (m, 2H); 7.51 (d, 1H, J=13.53 Hz); 7.97 (d, 1H, J=13.54 Hz).
