Reaction Steps

Following the procedure of Example 1 but using 4-(4-Chloro-phenyl)-4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-piperidine instead of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole and 4-bromo-1H-pyrazole-3-carbonitrile instead of 2-(4-chlorophenyl)-2-phenylethylamine hydrochloride gave the title compound. LC/MS: (PS-A2) Rt 2.22 [M+H]+ 363. 1H NMR (Me-d3-OD) δ 2.52-2.70 (4H, m), 3.10-3.20 (4H, m), 7.25 (4H, s), 7.37 (2H, d), 7.58 (2H, d), 8.02 (1H, s).
