Participants

Reaction Steps

8-(1-(3-chloro-2-fluorophenylamino)ethyl)-2-morpholino-4-oxo-4H-chromene-6-carboxylic acid (130 mg, 0.29 mmol) was reacted with piperidin-4-ol (35.3 mg, 0.35 mmol) using a procedure similar to the one described in Example 2.00 to give 8-(1-(3-chloro-2-fluorophenylamino)ethyl)-6-(4-hydroxypiperidine-1-carbonyl)-2-morpholino-4H-chromen-4-one (101 mg, 65.5%) as a white solid.
