実験手順: To a suspension of Compound 239 (150 mg, 0.38 mmol) in pyridine (2.0 mL) was added 3-(dimethylamino)propanoyl chloride (71 mg, 0.38 mmol) and the reaction mixture was heated at 105° C. for 5 h. and quenched with aqueous NH4Cl solution. Organic matter was extracted with CH2Cl2 (with 10% EtOH) and washed with brine. The organic extracts were dried (Na2SO4) and concentrated and purified by preparative HPLC to yield the title compound (103 mg, 55%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.16 (t, J=7.33 Hz, 3H) 2.24 (s, 3H) 2.33 (s, 6H) 2.56 (t, J=5.81 Hz, 2H) 2.62 (t, J=5.31 Hz, 2H) 3.41 (d, J=7.33 Hz, 2H) 3.93 (s, 3H) 7.41 (d, J=1.26 Hz, 1H) 7.87 (t, J=7.71 Hz, 1H) 7.93-7.97 (m, 1H) 8.03 (d, J=8.84 Hz, 1H) 8.06 (s, 2H) 8.22 (d, J=2.02 Hz, 1H) 10.99 (br. s., 1H) 12.07 (s, 1H); [M+H] calc'd for C26H31N4O-4S, 495.2; found, 495.4. quenched with aqueous NH4Cl solution Organic matter was extracted with CH2Cl2 (with 10% EtOH) washed with brine The organic extracts were dried (Na2SO4) concentrated purified by preparative HPLC
