실험 절차

0.41 ml of triethylamine is added to a solution of 0.5 g of the compound obtained in EXAMPLE 11, step B), in 10 ml of DCM, the mixture is then cooled to 0° C. and 0.14 ml of benzyl chloroformate is added dropwise. The reaction mixture is washed twice with water, dried over MgSO4 and concentrated under vacuum. The residue is chromatographed on silica gel H using DCM and then a DCM/MeOH mixture (94/6; v/v) as the eluent. The product obtained is taken up with DCM, acidified to pH 1 by the addition of hydrochloric ether and concentrated under vacuum to give 0.39 g of the expected hydrochloride after crystallization from iso ether. M.p.=135° C.
