Reaction Steps

Ten mL of 0.6M (CH3)2AlNH2 /benzene was added to 200 mg (0.45 mmol) of 4-[[3-(2-amino-2-oxoethyl)-2-methylthio-1-(phenylmethyl)-1H-indol-5-yl]oxy]butanoic acid ethyl ester (Example 46) in 25 mL of benzene and the mixture heated at 50° C. for 1.75 hours. After cooling the mixture was decomposed with ice and 1N HCl added. The mixture was extracted with EtOAc, the EtOAc solution washed with saturated NaCl solution, dried (Na2SO4), and concentrated at reduced pressure. The residue was crystallized from EtOH/CH2Cl2 to give 155 mg (84% yield) of 5-(4-amino-4-oxobutoxyl-2-(methylthio)-1-(phenylmethyl)-1H-indole-3-acetamide, mp, 185° C.
