Procedure
The title compound was prepared by the method outlined for Preparative Example 59 using 5-bromo-3-cyclobutyl-1H-indazole intermediate (225 mg, 0.898 mmol), NaH (41 mg, 1.02 mmol), and chloroacetonitrile (78 mg, 1.03 mmol) to afford titled compound as an off-white solid (160 mg, 62%). 1H NMR (DMSO-d6) 7.99 (s, 1H), 7.72 (d, J=8.8, 1H), 7.62 (d, J=8.8, 1H), 5.74 (s, 2H), 3.91 (pent, J=8.8, 1H), 2.38-2.32 (m, 4H), 2.08-2.06 (m, 1H), 1.95 (m, 1H). LC/MS (Method B) 3.99 min, [M+1]+ 290/292].
