실험 절차

Thiophosgene (146 μL, 1.92 mmol) was added to a solution of Example 45C (580 mg, 1.6 mmol) and DIEA (670 μL) in THF (10 mL). After stirring for 1 h, the reaction was poured over aqueous ammonia and extracted with EtOAc. Organics were dried (MgSO4) and concentrated. The resulting crude thiourea was dissolved in THF (5 mL). Bromopyruvic acid (320 mg, 1.92 mmol) was added, and the reaction stirred for 2 h. Purification by silica gel chromatography (10% MeOH/CHCl3) gave 590 mg (75%) of the title compound as a tan solid. H1-NMR (MeOD-d4): δ 9.95 (br s, 1H), 8.81 (br s, 1H), 7.87-7.96 (m, 4H), 7.60 (br s, 1H), 7.14 (s, 1H), 6.86 (s, 1H), 5.41 (s, 2H), 4.09 (s, 3H), 3.94 (s, 3H). MS (ES) (M+H) calc'd for C24H18N4O6S, 491; found 491.
