The general procedure for the synthesis of (R)-5-bromo-3-(1-methyl-2-pyrrolidinylmethyl)-1H-indole from the compound (CAS:1196663-29-2) is as follows:
Example 26; Preparation of BIP from BIP oxalate salt
BIP oxalate (170 g, 0.4435 mol) and deionized water (1500 mL) were stirred at 15 °C. The pH was adjusted to 7.8 using aqueous sodium carbonate (70.5 g, 0.6650 mol, dissolved in 200 mL of deionized water.) Toluene (1000 mL) was added and stirred for 30 min at 30-35°C. The organic and aqueous layers were separated and the aqueous layer was extracted with toluene (500 mL). Separate the organic and aqueous layers again. The organic layer was combined and washed with 10% (w/v) sodium carbonate aqueous solution. After separating the organic and aqueous layers, the organic layer was concentrated to 70% of the original volume (~1050 mL) at 50-55°C under reduced pressure. The concentrate was gradually cooled to 5-10 °C with stirring to precipitate a solid product. The solid was collected by filtration and washed sequentially with cold toluene (100 mL) and n-heptane (100 mL). After drying, 117.0 g of product was obtained; yield: 90.5%; purity: 99.12% (as BIP). | [References]
