N-(3-bromophenyl)-3-pyrrolidin-1-ylpropanamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 1M solution of BH3 in tetrahydrofuran (10 ml, 10 mmol) was added dropwise to N-(3-bromo-phenyl)-3-pyrrolidin-1-yl-propionamide (0.3 g, immol) and the solution was stirred overnight at reflux then subsequently hydrolysed by slow addition of excess of methanol and refluxing for a further 2 hours. The solvent was removed under reduced pressure and aqueous ammonium chloride was added. The aqueous phase was extracted twice with ethyl acetate and the organics were combined, dried over anhydrous magnesium sulfate and concentrated in vacuo. The resulting residue was dissolved in methanol and loaded onto an SCX cartridge, which was washed with methanol and the product subsequently eluted with 2M ammonia in methanol. Removal of all solvents under rotary evaporation gave the desired product. Yield 0.23 g, 82%. LCMS method: 2, RT: 2.71 min; MI: 283-285 [M+1]. at reflux refluxing for a further 2 hours The solvent was removed under reduced pressure and aqueous ammonium chloride was added The aqueous phase was extracted twice with ethyl acetate dried over anhydrous magnesium sulfate concentrated in vacuo The resulting residue was dissolved in methanol was washed with methanol the product subsequently eluted with 2M ammonia in methanol Removal of all solvents under rotary evaporation
