Reaktionsschritte

A mixture of 1.40 g of the product from stage 1 and 3.40 g of pyridinium dichromate in 350 ml of anhydrous dichloromethane was stirred for 24 hours at 20° C. The solution was then filtered and the filtrate was concentrated by evaporation in vacuo. The residue was purified by flash chromatography on silica gel with ethyl acetate/cyclohexane (1/1) as eluent, 0.88 g (64% of theory) of the title compound being obtained in crystalline form.
