(S)-2-aminopropanamide hydrochloride → HCID 9850447, compound

Participants

Reaction Steps

L-Alaninamide hydrochloride (0.151 g, 1.209 mmol) was dissolved in anhydrous DMF and DMAP (0.197 g, 1.612 mmol) was added to the solution. The reaction mixture was stirred at room temperature for 1 h. Then, (R)-5-(4-cyano-benzyl)-7-(3,5-dichloro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-sulfonyl chloride (0.24 g, 0.484 mmol) in anhydrous DMF was added to the reaction mixture and stirred for additional 10 min. The reaction solution was diluted with EtOAc and washed with water, 1 N HCl and then water. The organic phase was dried over Na2SO4 and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography to afford 0.211 g of the title compound as a white scaly solid (M+1, 547.2).
