| | 5-Methoxy-2-nitrobenzaldehyde Usage And Synthesis |
| Uses | 5-Methoxy-2-nitrobenzaldehyde is a starting material used to synthesize a novel class of cis-locked combretastatins named combretabenzodiazepines which shows cytotoxic and antitubulin activity. | | Synthesis | Step 1. Synthesis of 5-methoxy-2-nitrobenzaldehyde: 5-hydroxy-2-nitrobenzaldehyde (1 eq.), iodomethane (1.1 eq.) and potassium carbonate (1 eq.) were dissolved in DMF at room temperature and the reaction was stirred for 16 hours. Upon completion of the reaction, the reaction mixture was concentrated and subsequently partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated to give 5-methoxy-2-nitrobenzaldehyde in quantitative yield. Mass spectrometry analysis showed the molecular ion peak [M+H]+ = 182. | | References | [1] Patent: US2005/85482, 2005, A1. Location in patent: Page/Page column 13; 17
