Reaction Steps
A solution of tert-butyl (1R/S)-2-methoxy-1-[3-(2-{[5-methyl-4-(2-{[(3-methyl-1H-indol-5-yl)methyl]amino}-2-oxoethyl)-3-oxo-3,4-dihydro-2-pyrazinyl]amino}ethyl)phenyl]ethylcarbamate (preparation 124) (26 mg, 0.043 mmol) in hydrochloric acid (2 ml, 6N, 12 mmol) and methanol (2 ml), was stirred under a nitrogen atmosphere for 3 hrs. The reaction mixture was basified to pH 10 using 1N NaOH solution, extracted with dichloromethane (4×10 ml), and ethyl acetate (3×10 ml). The combined organic extracts were dried over MgSO4, and evaporated under reduced pressure to give the title compound as a white solid, (13 mg, 60%). Both R, and S isomers are present although their relative proportions have not been determined.
