YieldReaction ConditionsOperation in experiment
With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; N-ethyl-N,N-diisopropylamine; In N,N-dimethyl-formamide; at 20℃; Example 113.2-Cyclopropyl-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (l-methanesulfonyl-piperidin-3- lmethyl)-amideStep 1A 10 mL round-bottomed flask was charged with 2-cyclopropyl-5-((2- (trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (250 mg, 0.75 mmol), 3-(aminomethyl)-l-N-Boc-piperidine (241 mg, 1.12 mmol), HOBT (111 mg, 0.82 mmol) and EDC (158 mg, 0.82 mmol). Then added DMF (3.3 mL) followed by N,N- diisopropylethylamine (0.20 mL, 1.12 mmol). The yellow reaction mixture was stirred at room temperature overnight then quenched with H20 (5 mL) and extracted with Et20 (2 x 50 niL). The combined organic layers were washed twice with H20 and once with brine then dried over Na2S04, filtered and concentrated. The residue was purified by chromatography over 24g Si02 using EtOAc/Hexanes (gradient: 0-40percent EtOAc) to afford 393 mg (99percent) of 3- ({ [2-cyclopropyl-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7- carbonyl]-amino}-methyl)-piperidine-l-carboxylic acid tert-butyl ester as a pale yellow oil
