Reaction Conditions

Reaction Steps

To a solution of (3H-imidazol-4-ylmethyl)-(3-methoxy-phenyl)-amine (0.05 g, 0.25 mmol, Example 186 step a) in 1,2-dichloroethane (2 ml) were added pyridine-4-carbaldehyde (0.06 ml, 0.64 mmol) and sodium triacetoxyborohydride (0.21 g, 0.98 mmol). The reaction mixture was stirred at 40° C. for 72 h. The reaction mixture was then concentrated in vacuo and the residue was purified using flash chromatography (column: Isolute® Flash-NH2 (Separtis); eluent: methanol/dichloromethane gradient) to yield a yellow oil (7 mg, 10%); MS (ISP): 295.3 ((M+H)+.).
