Reaction Conditions:
in isopropyl alcohol;Reflux;
Steps:
13 Preparation of α,α'-[[(phenylmethyl)imino]bismethylene]bis[6-fluoro-3,4-dihydro-2H-1-benzopyran-2-methanol] (Formula IV', where P=benzyl)
EXAMPLE 13 Preparation of α,α'-[[(phenylmethyl)imino]bismethylene]bis[6-fluoro-3,4-dihydro-2H-1-benzopyran-2-methanol] (Formula IV', where P=benzyl) A round bottom flask is charged with [(R*S*)+(R*R*)]-6-fluoro-2-(oxiran-2-yl)chroman (25.3 g), isopropyl alcohol (350 mL), and benzylamine (6 g). The mixture is stirred under reflux conditions and reaction completion is verified using TLC. The solvent is distilled under vacuum below 50-55° C., to afford the title compound (35 g, ~100% yield).
