Participants

Reaction Steps

A solution of 3-(2-pyridin-4-yl-thiazol-4-yl)-1H-quinolin-2-one-7-carbaldehyde (step (a), 100 mg, 0.3 mmol), 1.5 mL AcOH, 1.5 mL of triethyl orthoformate, isopropylamine (0.5 mL), and 30 mL of DMF was stirred for 3 h. Gentle heating was be used to bring about a homogenous solution. After 3 h, NaBH(OAc)3 (0.5 g, Aldrich) was added and the reaction was stirred for 3 days at RT. The solution was concentrated in genevac overnight to remove DMF. The resulting solid was dissolved in a minimal amount of DMSO and purified by mass triggered HPLC to give a yellow solid after drying in genevac (TFA salt). MS m/z: 377.3 (M+1).
