Hydrogen Peroxide → HCID 15488980, compound

Participants

Reaction Steps

The product of Stage 95d (100 mg; 0.25 mmol) is dissolved in a mixture of water (1.33 ml) and sulphuric acid at 95% (1 ml). Heptahydrated iron (III) sulphate (28 mg; 0.10 mmol); valeraldehyde (0.17 ml; 1.60 mmol) are added to this solution and the resulting solution is cooled down with an ice bath. The reaction medium is then treated dropwise with hydrogen peroxide at 30% (0.38 ml; 1 mmol); agitated for 5 hours at ambient temperature, then diluted with water (50 ml) and extracted with dichloromethane (4×50 ml). The combined extracts are washed with water and with a saturated aqueous solution of sodium chloride, then dried over magnesium sulphate and concentrated under reduced pressure. The residue is purified by chromatography at medium pressure (SiO2, MeOH/CH2Cl2, 5/95) in order to produce the expected solid (m.p.>275° C.).
