A solution of 24 (10.7 mg, 0.024 mmol) in CH2Cl2 (0.24 mL) was stirred with EDC (14 mg, 0.73 mmol) and diethyl amine (10 μL, 0.097 mmol) for 1 day at ambient temperature. The product 25 was purified by reverse phase HPLC using 5-95% A. Buffer A contained CH3CN—1% HOAc and B contained H2O—1% HOAc. 1H NMR (300 MHz, CDCl3) δ 0.984 (t, 3H, J=6 Hz), 1.05 (t, 3H, J=7 Hz), 2.23-2.45 (m, 4H) 3.04 (q, 2H, J=7 Hz), 3.29 (q, 2H, J=8 Hz), 4.06 (s, 3H), 4.47 (d, 1H, J=14 Hz), 5.31 (d, 1H, J=15 Hz), 5.50 (s, 1H), 7.05 (t, 2H, J=9 Hz), 7.36-7.44 (m, 2H), 7.55-7.62 (m, 1H), J=9 Hz), 8.95-9.00 (m, 1H); EI MS (m/z) 520.2 [MH+], 1016.9 [2M+Na].
