Reaktionsschritte

In a similar manner to Step 2 of Example 440, 4-chloro-5-(3-chloropropoxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (119 mg, 0.208 mmol) was dissolved in N,N-dimethylacetoamide (1.2 mL), and the solution was treated with (S)-(+)-2-pyrrolidinemethanol (0.205 mL, 2.08 mmol). The reaction mixture was added with water. The obtained solid was collected by filtration and washed with water, followed by drying under reduced pressure to obtain (S)-4-chloro-5-[3-(2-hydroxymethylpyrrolidin-1-yl)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (91.0 mg, yield 69%).
