Versuchsvorschrift
A solution of methyl 4-aminobenzoate (0.25 g, 1.654 mmol) in tetrahydrofuran (8.27 ml) was treated with diisopropylethylamine (0.433 ml, 2.481 mmol) and 2-cyclopentylacetyl chloride (0.279 g, 1.902 mmol) and the reaction mixture was stirred at ambient temperature for 2 hours. Concentration and normal phase chromatography provided the title compound.
