Reaction Steps
DIEA (188 4l, 1.10 mmol) was added to a solution of 1-iodohexadecane (176 mg, 0.500 mmol), captopril (120 mg, 0.550 mmol) and DBU (165 pl, 1.10 mmol) in tetrahydrofuran (5 ml). The mixture was heated at 70° C. for 2 hours and then concentrated. The residue was poured onto water saturated with potassium hydrogen sulphate and organic material was extracted into chloroform. The organic phase was washed with water and dried (MgSO4). The product was purified by chromatography (silica, CHCl3/MeOH/AcOH 85:10:5) and lyophilised to give 105 mg (48%) of white solid material. The structure was verified by 1H (500 Mhz) and 13C (125 Mhz) NMR analysis and further characterised by MALDI mass spectrometry, giving M−H in negative mode at m/z 440 as expected.
