Synthetic Route of 29509-06-6,Some common heterocyclic compound, 29509-06-6, name is 4-Methyl-3-oxopentanenitrile, molecular formula is C6H9NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A solution of 4-methyl-3-oxo-pentanenitrile (Method 30; 0.42 g, 3. 78 mmol) and hydrazine monohydrate (0.183 ml, 3.78 mmol) inEtOH (20 ml) was heated to reflux for 1 hour, cooled, and then concentrated under reduced pressure. The resulted oil was dissolved with DCM, washed with brine, dried over anhydrousNa2S04, concentrated, and purification by column chromatography (EtOAc:MeOH = 20: 1) to the title compound as an orange solid (0.26 g,56%). 1H NMR (400 MHz,CDC13) 8 1.21-1. 23 (d, J= 7.0 Hz, 6 H), 2.82-2. 89 (q, 1 H), 5.42 (s, 1 H). MS: Calcd.: 125; Found:[M+H] + 126.
The synthetic route of 29509-06-6 has been constantly updated, and we look forward to future research findings.
