Chlorobenzene → HCID 57543425, compound

Participants

Reaction Steps

Palladium acetate (5.6 mg, 0.025 mmol), mono-methyl isophthalate (90 mg, 0.5 mmol) and chlorobenzene (283 mg, 2.5 mmol), butyldi-1-adamantylphosphine (19.2 mg, 0.05 mmol), Cs2CO3 (358 mg, 1.1 mmol), molecular sieves 3 Å (155 mg) and anhydrous DMF (2.5 mL). After the reaction and workup the residue was dissolved in methanol (10 mL) and cooled to 0° C. (Trimethylsilyl)diazomethane in hexanes (5.0 ml of a 2.0M solution, 1 mmol) was added dropwise, the cooling bath was removed and the mixture stirred for 5 h. The solvent was removed under reduced pressure. Purification by preparative HPLC afforded 101 mg (75%) of a colorless oil. Analytical data are consistent with that of previously reported data.4 1H NMR (300 MHz, CDCl3) δ 3.67 (s, 3H), 3.95 (s, 3H), 7.30-7.47 (m, 6H), 8.15-8.18 (m, 1H), 8.5 (br s, 1H). The 1H NMR spectrum is shown in FIG. 38.
