Reaktionsschritte

To a stirred solution of 1-Boc-3-pyrrolidinol (1 g, 5.34 mmol; available from Sigma-Aldrich #706620) and 4-(Trifluoromethyl)phenol (0.86 g, 5.34 mmol) in dry tetrahydrofuran (10 ml), Triphenylphosphine (1.54 g, 5.87 mmol) and diisopropyl azodicarboxylate (1.15 ml, 5.87 mmol) were added. The reaction mixture was stirred at room temperature for 2 days. Solvents were evaporated in vacuo and the residue was loaded on SPE-Si (25 g) cartridge and purified eluting with a mixture petroleum ether/ethylacetate (from 100/0 to 80/20). Collected fractions gave, after evaporation, the title compound (D34) (1.8 g).
