2-PROPOXYPHENYLBORONIC ACID

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 7-Bromo-2-butyl-1-isobutyl-1 H-imidazo[4,5-c]quinolin-4-amine and 2-propoxybenzeneboronic acid were coupled according to the general procedure described in Part J of Example 1. The product was recrystallized from isopropanol, collected by filtration, dissolved in CH2Cl2, and then precipitated with hexanes to afford 2-butyl-1-isobutyl-7-(2-propoxyphenyl)-1H-imidazo[4,5-c]quinolin-4-amine as a white powder, m.p. 174.5–176.0° C. The product was recrystallized from isopropanol collected by filtration dissolved in CH2Cl2 precipitated with hexanes

実験手順: A solution of benzoic acid N′-[2-(2-bromo-4-fluoro-phenoxy)-acetyl]-N′-isopropyl-hydrazide (50 mg, 0.122 mmol) in DME (3 ml)/2M Na2CO3 (0.215 ml, 0.427 mmol) was treated with 2-propoxyphenylboronic acid (33 mg, 0.183 mmol) and Pd[PPh3]4 (27 mg, 0.0244 mmol) for 12 hours at 90° C. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude was purified first on a silica gel column with a 20-30% ethyl acetate/hexanes gradient and then by RP HPLC to afford the product as a white solid (42 mg, 74%). MS m/e 407.23 (M+H+) The reaction mixture was partitioned between water and ethyl acetate The organic layer was washed with brine dried over sodium sulfate filtered concentrated The crude was purified first on a silica gel column with a 20-30% ethyl acetate/hexanes gradient
