Reaction Steps

The title compound was prepared by using the same method as described for 5-(5-(3,5-dichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-3,3-diethyl-benzo[c][1,2]oxaborol-1(3H)-ol with cyclopentanone to replace 3-pentanone. It was obtained as a white solid. 1H NMR (300 MHz, DMSO-d6): δ 9.20 (s, 1 H), 7.80 (t, J=1.8 Hz, 1 H), 7.72 (s, 3 H), 7.61 (d, J=1.5 Hz, 2 H), 4.44 (d, J=18.3 Hz, 1 H), 4.31 (d, J=18.3 Hz, 1 H), 2.11-1.71 (m, 8 H) ppm.
