(2S)-2-amino-N,N-dimethylpropanamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of the crude product containing N,N-dimethylalaninamide obtained in C) and triethylamine (2 mL) in ethanol (20 mL) was added 4-thioxothiazolidin-2-one (1998 mg) at room temperature. The reaction mixture was stirred at room temperature overnight, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (960 mg). the solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane)
