(±)-[2R*[1S*,5S*(S*)]]+[2R*[1S*,5R*(R*)]]-α,α'[iminobis(methylene)]bis[6-fluoro-3,4-dihydro-2H-1-benzopyran-2-methanol] (142 g) was converted into the hydrochloric acid salt in ethanol (1000 ml). The crystals were filtered off and crystallized from ethanol. The second fraction of the crystallization was recrystallized from ethanol, yielding 10.3 g (6.6%) of (±)-[2R*[1S*,5S*(S*)]]-α,α'[iminobis(methylene)]bis[6-fluoro-3,4-dihydro-2H-1-benzopyran-2-methanol]hydrochloride; mp. 224.9° C. nebivolol hydrochloride (crystalline compound 1).
