1-Naphthaldehyde → HCID 136088304, compound

Participants

Reaction Steps

To a solution of 5-aminotetrazole (0.850 g, 10.0 mmole) and triethylamine (0.250 ml, 1.8 mmole) in hot ethanol (25 ml) was added 1-naphthaldehyde (1.36 ml, 10.0 mmole) followed by 2-tetralone (1.32 ml, 10.0 mmole). The mixture is refluxed for 72 h after which time a small amount of powdery precipitate is observed. Upon cooling the reaction to room temperature, it was filtered and washed with ethyl ether to provide the desired product (0.189 g, 5.1%) as a tan powder. 1H NMR (400 MHz; DMSO-d6) δ 10.9 (bs, 1H); 9.0 (bs, 1H); 8.05-7.85 (m, 2H); 7.77 (at, 1H, J=7.0 Hz); 7.65 (at, 2H, J=7.0 Hz); 7.42 (at, 1H, J=7.4 Hz); 7.14 (d, 1H, J=7.4 Hz); 7.0-6.75 (m, 3H); 3.0-2.6 (m, 4H). LC MS shows MH+ at 352; 2M+H at 703 and 2M+Na at 725.
