Participants

Reaction Steps

Trifluoroacetic acid (0.2 ml) was added to a dichloromethane solution (0.3 ml) containing 11.5 mg (0.0227 mmol) of t-butyl 4-{2-[7-(3-hydroxypiperidin-1-yl)-1-oxo-1,2-dihydroisoquinolin-3-yl]phenyl}piperazin-1-carboxylate obtained in Example 101. The obtained mixture was stirred at a room temperature for 30 minutes. Thereafter, the solvent was distilled away under reduced pressure. The obtained residue was purified using BondElute NH2 (register trade mark; Varian; 1 g; dichloromethane:methanol=20:1), so as to obtain 8.9 mg (97%) of 7-(3-hydroxypiperidin-1-yl)-3-(2-piperazin-1-ylphenyl)-2H-isoquinolin-1-one in the form of a yellow solid.
