Reaction Steps

The titled compound (yield=25%, white solid) was prepared using a procedure analogous to that described in connection with 9 (Example 9) except 1D (Example 1) and 3,5-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole were used as starting materials. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.46 (s, 6H) 2.40 (s, 6H) 7.54 (d, J=8.34 Hz, 1H) 7.66 (d, J=8.34 Hz, 2H) 8.04-8.19 (m, 3H) 12.89 (br. s., 1H); ESI-MS: m/z 408.0 (M+H)+.
