Ethyl 2-(6-(4-(cyclobutyamino)-7H-pyrrolo[2,3-d]pyrimidine-2-ylamino)-2-oxo-3,4-dihydroquinolin-1(2H)-yl)acetate → 2-(6-(4-(cyclobutyamino)-7H-pyrrolo[2,3-d]pyrimidine-2-ylamino)-2-oxo-3,4-dihydroquinolin-1(2H)-yl)acetic acid

Participants

Reaction Steps

To a solution of ethyl 2-(6-(4-(cyclobutyamino)-7H-pyrrolo[2,3-d]pyrimidine-2-ylamino)-2-oxo-3,4-dihydroquinolin-1(2H)-yl)acetate (10 mg, 0.023 mmol) in THF (0.6 mL) and H2O (0.4 mL) was added NaOH (5N, 2 drops). After stirring for 3 h at room temperature, the reaction mixture was purified by preparative HPLC to yield 2-(6-(4-(cyclobutyamino)-7H-pyrrolo[2,3-d]pyrimidine-2-ylamino)-2-oxo-3,4-dihydroquinolin-1(2H)-yl)acetic acid (MS calcd for C21H22N6O3 406.2, found [MH] 407.0; UV 207.5, 304.5 nm).
