Sodium borohydride → HCID 13362029, compound

Participants

Reaction Steps

To 580 ml of methanol was added 72 g. of sodium borohydride at 0°-5°. After the addition, 40 g of methyl 1-benzyl-2-(2,6-dichlorophenyl)-5-oxopyrrolidin-3-carboxylate was then added in portions at 0°-5°. The reaction was stirred at 10°-15° and then left standing overnight at ambient temperature. After concentrating the mixture in vacuo to a solid, the crude product was suspended in water at 50° and stirred for 30 minutes. The resulting solid was collected by filtration and dissolved in chloroform. Drying (Na2SO4), filtration, and concentration in vacuo provided 48 g of off-white crystals, m.p. 122°-126°.
