Reaction Steps

Compound 105 (250 mg, 0.93 mmol) was suspended in pyridine (0.5 mL). Decanoyl chloride (141 mg, 0.74 mmol) was added slowly at 0° C. The reaction mixture was then heated to 95° C. and was stirred for 1 h. The reaction mixture was then added to aqueous 3 N HCl solution (5 mL) and the mixture extracted with ethyl acetate (3×10 mL). The organic extracts were washed with water (3×20 mL), brine (3×20 mL), dried over anhydrous Na2SO4, and filtered. Evaporation of the solvent left a residue which was crystallized from hexanes and ethyl acetate (1:2) to give the product (297 mg, 0.70 mmol, 95%) as a solid, mp 141-142° C.; 1H NMR (500 MHz, DMSO) δ 0.82 (3, t, J=7.0 Hz), 1.10-1.30 (12, m), 1.54-1.63 (2, m), 2.32 (2, t, J=7.0 Hz), 2.45 (3, s), 8.25 (2, d, J=8.0 Hz), 8.28 (2, d, J=8.0 Hz), 10.25 (1, s), 13.87 (1, s); 13C NMR (125 MHz, DMSO) δ 13.9, 16.0, 22.1, 24.9, 28.5, 28.6, 28.8, 28.9, 31.2, 36.4, 118.5, 126.8, 135.5, 142.7, 154.1, 167.6, 171.7; MS (LCQ, ESI+) Calculated for C19H29N4O3S2 425.2. found 425.1 (M+H)+. HRMS (FAB+, m/z) Calculated for C19H29N4O3S2 425.1681. found 425.1678 (M+H)+.
