Procedure
To a solution of 3-(tetrahydrofuran-2-yl)propanoic acid (11.5 g, 80.0 mmol) in anhydrous THF (200 mL) was added borane (160 mL, 160 mmol, 1 mol/L in THF) dropwise under N2 and the mixture was stirred at rt overnight. The reaction mixture was quenched with MeOH and concentrated in vacuo to give the title compound, which was used for next step without further purification.
