Reaction Steps
Preparation of example 151 from the title compound of Example 7 (hydrochloride) (40 mg, 0.128 mmol), (2R)-2-[{[(1,1-dimethylethyl)oxy]carbonyl}(methyl)amino]-3-(4-hydroxyphenyl)propanoic acid (57 mg, 0.192 mmol), triethylamine (0.054 mL, 0.384 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (73 mg, 0.192 mmol) in CH2Cl2 (0.4 mL) and N,N-dimethylformamide (0.4 mL) was carried out analogously to Example 11. Additional (2R)-2-[{[(1,1-dimethylethyl)oxy]carbonyl}(methyl)amino]-3-(4-hydroxyphenyl)propanoic acid (14 mg, 0.047 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (18 mg, 0.047 mmol) were added after 24 hours to drive the reaction to completion. Silica gel chromatography (eluted with 1:1 hexane:acetone), also in an analogous manner, afforded the title compound (55 mg, 0.099 mmol) as a yellow powder in 78% yield.
