Procedure
The mixture of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4-fluorophenyl)-1H-indazole-7-carbonitrile (Intermediate 11) (0.102 mmols) and potassium hydroxide (26 mg, 0.51 mmol) in 2-methyl-2-propanol (4 mL) was heated overnight. The reaction mixture was concentrated and purified by using a Gilson semi-preparative HPLC system with a YMC ODS-A (C-18) column 50 mm by 20 mm ID, eluting with 10% B to 70% B in 3.2 min, hold for 1 min where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) pumped at 25 mL/min to afford the title compound (21 mg, 48% for 2 steps)
