Reaction Steps
A microwave vial was charged with 6-bromo-5-nitro-1H-isochromen-1-one (500.00 mg, 0.0018516 mol), cyclopropylboronic acid (206.8 mg, 0.002407 mol), palladium acetate (21 mg, 0.000092 mol), tricyclohexylphosphine (52 mg, 0.00018 mol), potassium phosphate (1376 mg, 0.006481 mol), toluene (10 mL, 0.09 mol) and water and heated at 100° C. for 30 minutes under microwaves. The rection mixture was then diluted with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried and evaporated. The resultant residue was purified by flash chromatography to obtain the product. The product was only 65% pure and was used to synthesize 6-cyclopropyl compounds of this invention without further purification. MS m/z=232.3 (M+H). 1H NMR (400 MHz, DMSO-d6): δ 8.22 (d, J=8.63 Hz, 1H), 7.69 (d, J=5.85 Hz, 1H), 7.33 (d, J=8.47 Hz, 1H), 651 (d, J+6.05 Hz, 1H), 1.96-1.89 (m, 1H), 1.19-1.14 (m, 2H, 0.97-0.93 (m, 2H).
