Participants

Reaction Steps

Experimental condition analogous to Example 5, from benzo[b]thiophen-3-carbaldehyde 0.16 g (1 mmol), 2-(1-methyl-pyrrolidin-2-yl)-ethylamine 0.14 g (1.1 mmol), and sodium triacethoxyborohydride 0.31 g (1.5 mmol), in 10 mL Dichloromethane. Purification using silica chromatography, elution with dichloromethane-methanol-ammonium hydroxide, 9-1-0.25, gave 140 mg of compound.
