実験手順
A mixture of 2-(3-methyl-1,2,4-oxadiazol-5-yl)benzoic acid (CAS number 475105-77-2; 0.84 g, 4.12 mmol), tert-butyl N-[(1S,2S)-2-aminocyclopentyl]carbamate (CAS number 586961-34-4; 0.75 g, 3.74 mmol), HATU (2.14 g, 5.62 mmol) and triethylamine (1.57 ml, 11.23 mmol) was stirred in dry DMF (12.5 ml) at room temperature for 17 hours. The reaction mixture was partitioned between ethyl acetate and water, washed with water and brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The crude material was then purified by column chromatography (silica, 0-100% ethyl acetate/petrol). The resulting cream solid was recrystalised from ethyl acetate, to which was then added methanol (10 ml) and HCl in 1,4-dioxane (4M, 4.68 ml, 18.72 mmol) and the reaction was stirred at room temperature for 17 hours. The reaction was concentrated in vacuo and azeotropically distilled with toluene to afford the title compound.
