Reaction Conditions

Reaction Steps

Compound 109 (250 mg, 0.88 mmol) was suspended in pyridine (1.3 mL). Decanoyl chloride (134 mg, 0.70 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 (4.5 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 (372 mg, 0.85 mmol, 97%) as a solid, mp 121-122° C.; 1H NMR (500 MHz, DMSO) δ 0.82 (3, t, J=7.0 Hz), 1.17-1.30 (14, m), 1.57 (2, t, J=7.0 Hz), 2.32 (3, t, J=7.0 Hz), 2.80 (2, q, J=7.0 Hz), 7.72 (2, d, J=8.5 Hz), 7.76 (2, d, J=8.5 Hz), 10.21 (1, s), 13.89 (1, s); 13C NMR (125 MHz, DMSO) δ 12.2, 13.9, 22.1, 23.6, 24.9, 28.6, 28.7, 28.8, 28.9, 31.2, 36.5, 118.5, 126.8, 135.5, 142.7, 159.7, 167.2, 171.8; MS (LCQ, ESI+) Calculated for C20H31N4O3S2 439.2, found 439.1 (M+H)+; HRMS (FAB+, m/z) Calculated for C20H31N4O3S2 439.1838, found 439.1843 (M+H)+.
