Reaction Steps
TFA (0.096 g, 0.00084 mol) was added to solution of 1-(4-methyl-pyridin-3-yl)-3-[1-(2-trimethylsilanyl-ethoxymethyl)-1H-indazol-5-yl]-imidazolidin-2-one (0.24 g, 0.00056 mol) in DCM (10 mL) at 0° C. The reaction mixture was stirred at room temperature overnight. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was concentrated and the concentrate was purified by preparative HPLC to afford 42 mg of the product (19.47% yield).
