YieldReaction ConditionsOperation in experiment
180 mg With potassium phosphate; at 180℃; for 0.25h;Microwave irradiation; Tert-butyl 4-(3-ethoxy-3-oxopropanoyl)piperidine-l-carboxylate (1.00 g, 3.34 mmol, 1.5 eq), 4-(4- bromophenyl)-3-methyl-lH-pyrazol-5-amine (585 mg, 2.27 mmol, 1 eq) and potassium phosphate (945 mg, 4.45 mmol, 2 eq) were suspended in l-methoxy-2-propanol (10 mL) in a 20 mL microwave vial. The vial was capped and the mixture was heated in a microwave to 180C for 15 min. After cooling to RT, the mixture was evaporated in vacuo, diluted with water (5 mL) and extracted with ethyl acetate (3x10 mL). The combined organic layers were dried with sodium sulfate, filtered and evaporated in vacuo. The residue was purified by preparative HPLC (Method 1A). The combined product fractions were adjusted to pH 7 by addition of aqueous ammonium hydroxide. Acetonitrile was evaporated in vacuo, the resulting suspension was filtered, the residue was washed with water (0.5 mL) and dried for 16 h at 50C in vacuo to give the title compound (180 mg, 16% of theory). LC-MS (Method IB): Rt = 1.23 min, MS (ESIPos): m/z = 487 [M+H]+
