Sorbinil is obtained by optical resolution of racemic 2,3-dihydrospiro-6-fluoro[4H-I-benzopyran-4,4 min -imidazolidine]-2 min ,5 min -S HY# dione either (a) by direct resolution via the (-)-3-aminomethylpinane salt of sorbinil or (b) by a double resolving agent technique via a mother liquor concentrate of either the (+)-3-aminomethylpinane or the (-)-2-amino-2-norpinane salt of sorbinil, followed by the quinine salt of sorbinil. |
