Reaction Steps

Sodium triacetoxyborohydride (277 mg, 1.31 mmol) was added to a mixture of the amine from example 12 (250 mg, 0.65 mmol), 2-pyridine carboxaldehyde (105 mg, 0.98 mmol), and acetic acid (3 drops) in dichloromethane (5 ml), cooled to 5° C., and the reaction mixture was then stirred at room temperature for 18 hours. 0.88 Ammonia was added to the reaction mixture, the phases were separated and the organic layer was dried over magnesium sulphate and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel using dichloromethane:methanol (95:5) as eluant, to afford the title compound (167 mg)
