Reaction Steps

To a 5-mL, round-bottomed flask was added [6-(2-amino-4-trifluoromethylphenyl)pyrimidin-4-yl]benzothiazol-6-ylamine (0.060 g, 0.15 mmol), 1,2-dichloroethane (1 mL), acetic acid (0.018 mL, 0.31 mmol) and cyclohexanecarboxaldehyde (0.055 mL, 0.45 mmol, Aldrich). Sodium triacetoxy-borohydride (0.083 g, 0.39 mmol, Aldrich) was added to the mixture with stirring at 0° C. and the mixture was stirring for 17 h at room temperature. The reaction mixture was diluted with EtOAc (3 mL) and quenched with H2O (3 mL) and satd NaHCO3 (7 mL). The phases were separated and the aqueous phase was extracted with EtOAc (3×3 mL). The combined organic extracts were washed with brine, dried over Na2SO4 and concentrated in vacuo onto silica gel. Purification by silica gel chromatography with gradient from 20% to 50% solution of EtOAc in hexane afforded the title compound as a yellow solid. MS (ESI, pos. ion.) m/z: 484 (M+1).
