実験手順

A solution of 4-(5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-2-methylbenzoic acid (0.3 g, 0.67 mmol) and DIPEA (346 mg, 2.68 mmol) in DMF (10 mL) was stirred at rt for 5 min and then HATU (510 mg, 1.34 mmol) was added. The mixture was stirred for 10 min prior to the addition of 6-(aminomethyl)-1H-spiro[benzo[c][1,2]oxaborole-3,1′-cyclo-pentan]-1-ol hydrochloride (202 mg, 0.80 mmol). And the resulting mixture was stirred at rt overnight. It was then concentrated under vacuum, and the residue was partitioned between 1N HCl and ethyl acetate. The organic layer separated was concentrated under vacuum, and the residue was purified on column chromatography and prep-HPLC to provide the product (150 mg, yield 34%). 1H NMR (400 MHz, DMSO-d6): δ 9.03 (s, 1H), 8.89 (t, 1H), 7.82 (s, 2H), 7.59 (t, 3H), 7.44 (m, 2H), 7.36 (d, 1H), 4.45 (d, 2H), 4.36 (d, 1H), 4.28 (d, 1H), 2.41 (s, 3H), 1.99 (m, 8H) ppm; HPLC purity: 98.37% at 220 nm and 98.66% at 254 nm; MS: m/z=652.
