反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 3-phenylpropyl isothiocyanate (500 mg, 2.82 mmol) and 2-aminothiazole (300 mg, 3.0 mmol) in N,N-dimethylformamide (10 mL) was heated to 100° C. After 20 h, the reaction was cooled to room temperature and poured into ethyl acetate. The organic phase was washed with 1N hydrochloric acid, water (3×), and brine. The organic layer was dried over sodium sulfate, filtered and concentrated. The solid obtained was purified by flash chromatography on silica gel (1% ethyl acetate in dichloromethane) and then recrystallized from ethyl acetate to provide 129 mg of the title product. A second crop was recrystallized from 1:1 ethyl acetate/hexanes to provide another 110 mg of the title product. Total yield of the title product: 239 mg (30%) as an off-white solid. A sample was recrystallized again from ethyl acetate: The organic phase was washed with 1N hydrochloric acid, water (3×), and brine The organic layer was dried over sodium sulfate filtered concentrated The solid obtained was purified by flash chromatography on silica gel (1% ethyl acetate in dichloromethane) recrystallized from ethyl acetate

实验步骤: An equimolar solution of N-(toluene-4-sulfonyl)-L-prolyl-4-amino-L-phenylalanine methyl ester and 3-phenylpropyl isothiocyanate in toluene was stirred at room temperature for 16 hr. The solvent was stripped off giving an amber oil which was submitted to preparatory HPLC (Waters silica cartridge; 85/15 CH2Cl2/EtOAc) for purification. The fractions were collected and the solvent removed yielding the title compound as a white solid, mp=74-80° C. giving an amber oil which was submitted to preparatory HPLC (Waters silica cartridge; 85/15 CH2Cl2/EtOAc) for purification The fractions were collected the solvent removed
