Versuchsvorschrift

To a solution of 30 (250 mg, 0.5 mmol) in 30 ml DMF was added HATU (250 mg, 0.66 mmol) and DIEA (400 uL, 2.2 mmol). After stirring for 2 hrs, ammonia gas was bubbled into the solution for 5 minutes using a glass inlet tube. The mixture was then stirred at ambient temperature overnight. Water was added (10 mL) and the solvent was removed under vacuum to give a yellow oil which was taken up in ethyl acetate and water (1:1). The organic layer was washed twice with water and then brine, and dried over Na2SO4. After filtration and concentration, the crude product was purified using silica gel chromatography (CH2Cl2/methanol 10:0.5) to give compound 31 (120 mg) as a white solid (48%). 1H NMR (CDCl3) 0.95-0.88 (dd, 6H), 1.32-1.28 (m, 1H), 1.64-1.50 (m, 1H), 1.90-1.80 (m, 1H), 2.35-2.00 (m, 1H), 2.80-2.54 (m, 4H), 3.48 (s, 3H), 5.38-5.14 (m, 5H), 5.54-5.51 (d, 1H), 5.90-5.78 (m, 2H), 7.65-7.25 (m, 9H), 8.52 (s, 1H). ESI ES+=523.2 (M+Na).
