実験手順

30.9 mg (0.13 mmol) of rac-cyclopent-1-en-1-yl(4-methoxypiperidin-1-yl)acetic acid were initially charged in 0.87 ml of DMF/pyridine (3:1), 63.8 mg (0.17 mmol) of HATU were added and the mixture was stirred at RT for 30 min 34.3 mg (0.13 mmol) of tert-butyl 1-(3-amino-4-fluorobenzyl)cyclopropanecarboxylate were then added, and the reaction mixture was stirred at RT overnight. The mixture was then diluted with ethyl acetate, washed repeatedly with saturated sodium chloride solution, dried over magnesium sulphate and concentrated under reduced pressure. The residue was purified by preparative HPLC (RP18 column; acetonitrile/water gradient with addition of 0.1% TFA, 10:90→95:5; run time 38 min). This gave 20.7 mg (33% of theory) of the title compound.
