86% | With sodium tris(acetoxy)borohydride; In 2-methyltetrahydrofuran; at 20℃; for 4.75h; | Intermediate 62 : 2-f3-f4-Methyl-3-oxopiperazin-l-vnpropynisoindoline-l,3- dione (0595) To a mixture of 3-(l,3-dioxoisoindolin-2-yl)propanal (515 mg, 2.53 mmol, commercially available from Fluorochem) and Na(OAc)3BH (815.9 mg, 3.85 mmol) in 2-MeTHF (20 mL) was added l-<strong>[59702-07-7]methylpiperazin-2-one</strong> (0.420 mL, 3.82 mmol, commercially available from Fluorochem). The mixture was stirred at rt for 4 h 45 min. To the reaction mixture was added aqueous 2M Na2C03 (10 mL) and this mixture stirred at rt for 10 min giving an aqueous phase at approximately pH 10. The layers were separated and the aqueous layer washed with EtOAc (2 x 10 mL). The organic layers were filtered through a cartridge fitted with a hydrophobic frit and the filtrate evaporated in vacuo to give a pale yellow crystalline solid. 2-(3-(4-methyl-3-oxopiperazin-l-yl)propyl)isoindoline-l,3-dione (660.5 mg, 2.192 mmol, 86 percent yield). (0596) LCMS (2 min high pH); Rt = 0.74 min, m/z = 302 for [MH]+ |
