Vorschrift

Preparation of example 50 from the title compound of Example 7 (30 mg, 0.11 mmol), 3-(2-methylphenyl)propanoic acid (27 mg, 0.16 mmol), triethylamine (0.076 mL, 0.55 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (62 mg, 0.16 mmol) in N,N-dimethylformamide (1.5 mL) was carried out analogously to Example 11. Silica gel chromatography (3% methanol in CH2Cl2 increasing to 5% methanol in CH2Cl2), also in an analogous manner, followed by methanol trituration afforded the title compound (6 mg, 0.014 mmol) as a yellow powder in 13% yield.
