Versuchsvorschrift

A solution of carboxylic acid 46 (240 mg, 0.38 mmol) and carbonyldiimidazole (2 eq) in dry THF (5 mL) was stirred at reflux under nitrogen for 2 h. The reaction mixture was cooled to room temperature and 1-methylcyclopropylsulfonamide (2 eq) and DBU (2 eq) were added. This solution was heated at 50° C. for 15 h. Then, the reaction mixture was cooled down to room temperature and concentrated under reduced pressure. The residue was partitioned between CH2Cl2 and HCl 1N, the organic layer was washed with brine, dried (MgSO4) and evaporated. Purification by flash chromatography (gradient of EtOAc (0 to 25%) in CH2Cl2) afforded 170 mg (58%) of the title compound 48 as an off-white solid which was further washed with water, then isopropylether, and dried in the vacuum oven: m/z=764 (M+H)+. 1H NMR (acetone-d6): 0.86 (m, 2H), 1.15-1.78 (m, 19H), 1.87 (m, 2H), 2.13-2.54 (m, 3H), 2.57-2.71 (m, 4H), 2.96-3.25 (m, 4H), 3.54 (m, 2H), 4.02 (s, 3H), 4.58 (t, J=13 Hz, 1H), 5.04 (m, 1H), 5.46 (m, 1H), 5.62 (m, 1H), 7.31 (s, 1H), 7.43 (d, J=9 Hz, 1H), 7.58 (s, 1H), 8.07 (d, J=13 Hz, 1H), 8.19 (broad s, 1H), 11.44 (broad s, 1H).
