Epirubicin hydrochloride intermediate compound

The invention provides a novel intermediate and a novel route for synthesizing epirubicin hydrochloride by utilizing the intermediate. The route is simple, cheap and efficient, achieves better energy conservation and emission reduction, and avoids the problems that an intermediate generated by the existing epirubicin hydrochloride synthesis route is water-instable and easy to decompose and a yield of the whole route is low. The route uses a low-cost and easy-to-obtain reagent and adopts a removable selective protection means; generated impurities are few; the purity is high; a yield is high.
