To a suspension of 2-(2-phenyl-chroman-6-yloxy)-thiazole-5-carbaldehyde (54 mg, 0.13 mmol) and pyridin-4-yl-methylamine (17 mg, 0.16 mmol, 1.2 eq) in tetrahydrofuran (3 ml) and acetic acid (0.5 ml) at 0° C. sodium cyanoborohydride (polymer bond, 2.19 mM/g, 137 mg, 0.30 mmol, 2.3 eq) was added and the mixture stirred at 40° C. for 16 h. The reaction mixture was filtered, the volatile components removed under reduced pressure and the remaining residue purified by reversed phase HPLC (water/acetonitrile gradient (+0.1% trifluoroacetic acid)) to give 30 mg (42%) of [2-(2-phenyl-chroman-6-yloxy)-thiazol-5-ylmethyl]-pyridin-4-ylmethyl-amine in the form of its salt with trifluoroacetic acid.
