(R)-3-氨基-2,3-二氢苯并[B][1,4]硫氮杂-4(5H)-酮盐酸盐

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 3-Amino-2,3-dihydro-1,5-benzothiazepin-4(5H)-one hydrochloride (1.0 g, 5.15 mmol, Eq: 1.00), BOC—N-Me-Ala-OH (1.26 g, 1.62 mmol, Eq: 1.2) and TEA (2.2 mL, 15.45 mmol, Eq: 3.00) were dissolved in DMF (30 mL) and HOBT.H2O (697 mg, 5.14 mmol, Eq: 1.20) and HBTU (2.34 g, 6.18 mmol, Eq: 1.20) were added. After 1 h 20 min. the mixture was diluted with 1 N HCl and extracted with EtOAc. The organic extracts were washed with 1 N NaOH, brine, dried over Na2SO4 and concentrated to afford the title compound (1.66 g, 85% yield) which was used without purification. extracted with EtOAc The organic extracts were washed with 1 N NaOH, brine dried over Na2SO4 concentrated
