It is left shaking overnight in these conditions. The following morning 450 ml of HCl 2N are added and the shaking continued for 24 hours. The THF is removed in the rotovapor and the resulting aqueous solution is extracted with AcOEt ( 2×200 ml), washed with a solution of 5% NaHCO3 and with a saturated NaCl solution, it is dried with sodium sulphate, filtered and the solvent evaporated with the rotovapor. In this way are obtained 54.6 g of a reddish liquid crude that solidifies.
