Reaction Steps

A solution of 4-(6′-cyclopropylamino-[2,2′;4′,3″]terpyridin-5″-yl)-benzaldehyde (Example 2.64)(1 eq, 0.204 mmol, 80 mg) in DCM (3 ml) is treated with (R)-pyrrolidin-3-yl-carbamic acid tert-butyl ester (2.2 eq, 0.448 mmol, 83.2 mg) followed by AcOH (1.2 eq, 0.245 mmol, 0.14 ml) and sodium triacetoxyborohydride (3.1 eq, 0.632 mmol, 134 mg). The reaction mixture is stirred at room temperature overnight and then extracted with DCM. The organic portion is washed with water, dried (MgSO4) and concentrated in vacuo to afford the title compound which is used in the next step without further purification; [M+H]+ 563.
