Reaction Steps

A flask was charged with 1-(methoxycarbonyl)-2-(2-((2-(trimethylsilyl)ethoxy)methyl)-7-methyl-2H-indazol-5-yl)ethyl 4-nitrophenyl carbonate (27 mg, 51 mmoles) and 3,4-dihydro-3-(piperidin-4-yl)quinazolin-2(1H)-one (34 mg, 2.8 equiv). The solids were dissolved in dimethylformamide (1 mL) and treated with diisopropylethylamine (0.1 mL, 11 equiv). The reaction was stirred at room temperature for 2 d. The reaction was concentrated, dissolved in ethyl acetate, washed with 20% potassium hydroxide (3×), then brine, dried over magnesium sulfate, and concentrated. Column chromatography (100% ethyl acetate) removed baseline material to give 50 mg (quant.). Mass spec.: 622.50 (MH)+.
