Reaction Steps

Compound 100 (50 mg, 0.20 mmol) was suspended in pyridine (0.3 mL). Decanoyl chloride (39.1 mg, 0.21 mmol) was added gradually over 15 min. The reaction mixture was heated to 95° C. and stirred at this temperature for 1 h, then poured into 10% aqueous HCl solution and extracted with EtOAc (3×0.5 mL). The combined organic extracts were washed with water (3×5 mL), brine (3×5 mL), and dried over anhydrous Na2SO4. Evaporation of the solvent yielded the product (80 mg, 0.20 mmol, 95%). It was recrystallized from hexanes/ethyl acetate to yield an analytical sample, mp 151-152° C.; 1H NMR (250 MHz, CD3OD) δ 0.88 (3, t, J=7.5 Hz), 1.24-1.45 (12, m), 1.68 (2, t, J=7.5 Hz), 2.37 (2, t, J=7.5 Hz), 7.72 (2, d, J=8.5 Hz), 7.79 (2, d, J=8.5 Hz), 8.49 (1, S); 13C NMR (125 MHz, CD3OD) δ 14.4, 23.7, 26.7, 30.3, 30.4, 30.5, 30.6, 33.0, 38.1, 102.4, 128.3, 137.5, 144.0, 145.0, 170.0, 174.9; MS (ESI+) 411.1 (M+H)+; HRMS (IonSpec. HiRES ESI+) calcd. for C18H27N4O3S2 (M+H)+ 411.1525. obsd. 411.1524.
