Reaction Steps

2-Chloro-N-(3-methanesulfonyl-5-nitro-phenyl)-acetamide (750 mg; 2.56 mmol) was diluted in 40 of ethyl acetate, (R)-(−)-2-amino-1-butanol (1.01 ml; 10.25 mmol) was added and the reaction mixture was stirred at 75° C. overnight. The solvent was concentrated under vacuum and the crude was purified by flash chromatography (Isolute Silica cartridge 10 g; eluent: Dichloromethane:MeOH=99:1). 380 mg (1.10 mmol; 43% yield) of the desired 2-((R)-1-Hydroxymethyl-propylamino)-N-(3-methanesulfonyl-5-nitro-phenyl)-acetamide were obtained.
