The solid thus obtained was partially dissolved in ethyl acetate (100 ml), subsequently filtered and the liquid phase obtained was concentrated under vacuum obtaining a reaction raw product. The reaction raw product thus obtained was purified by means of column chromatography [silica gel, gradients from n-heptane 100% to n-heptane/ethyl acetate = 8:2 (v/v) as eluent] obtaining 1060 mg (67.4% in moles) of Compound (6).
