Reaction Steps

The 7-((R)-4-benzyloxymethyl-3-methyl-2-oxoimidazolidin-1-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (13 mg, 0.025 mmol) prepared in Example 1-35 was dissolved in methanol (5 ml). Thereafter, 10% Pd—C (3 mg) was added to the obtained solution, and the obtained mixture was then stirred in a hydrogen atmosphere for 3 hours. The reaction solution was filtered through celite, and the filtrate was then concentrated. The obtained residue was purified by silica gel TLC used for preparative separation (dichloromethane:methanol=20:1), so as to obtain 7-((R)-4-hydroxymethyl-3-methyl-2-oxoimidazolidin-1-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (10.9 mg, quantitative) in the form of a white solid.
