실험 절차
The title product of Example 34 (150 mg, 0.34 mmol) was added to a solution of thiolactic acid (100 μL, 1.14 mmol) and KOH (150 mg, 2.7 mmol) in degassed DMF (5 mL)/H2O (0.5 mL). The reaction mixture was stirred at 50° C. under an atmosphere of N2 for 72 hours and then cooled to room temperature. The pH of the mixture was adjusted to about 4.0 with acetic acid and then partitioned between CHCl3 and brine. The organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by preparative RP18 HPLC utilizing a gradient of 15% to 100% CH3CN/pH 4.5, 50 mM ammonium acetate followed by lyophilization of the appropriate pure fractions to afford the title product (28 mg; 18%; M.P. 95°-103° C. (dec); LC-MS: 468 (MH+); anal. RP-HPLC RT: 3.57 min).
