Reaction Steps

To an ice water-cooled solution of (3S)-3-(4-aminophenoxy)piperidine (3.5 g) in DMF (20 mL) was added K2CO3 (7.5 g) and Nal (0.2 g), followed by the addition of 5-chloromethyl-1,3-benzodioxole (4.7 mL). The resulting reaction mixture was stirred at ambient temperature for 2 hours. The reaction mixture was diluted with ethyl acetate (200 mL), washed with water (100 mL×3) and brine (100 mL), and dried (Na2SO4). The crude product was further purified by column chromatography (methanol:ethyl acetate1:10), to afford (3S)-3-(4-aminophenoxy)-1-[(1,3-benzodioxol-5-yl)methyl]piperidine (4.4 g, 74% yield) as an oil.
