実験手順

Combine 4-benzyloxy-2-butanone (1.78 g, 10 mmol) with 2-amino-1-(4-hydroxy-3-methylsulfinylphenyl)ethanol (10 mmol) in methanol (50 ml) and add sodium cyanoborohydride (0.63 g, 10 mmol). Let stand 16 hours, concentrate the solution and purify the crude product by chromatography on silica gel using chloroform: methanol: ammonium hydroxide (70:27:3) as eluent to obtain the title compound.
