To a solution of 3-(tetrahydro-3-furanyl)propanoic acid (1 g, 6.94 mmol) in dry THF (20 ml) at 0° C. was added a 1M solution of Boron THF complex (21.16 ml, 21.16 mmol) in THF dropwise over 2 mins. The mixture was stirred at 0° C. for 1 hour then allowed to warm to room temperature and stirred for 18 h. The reaction mixture was cautiously quenched with methanol (˜20 ml) and the solvent removed in vacuo. The residue was re-dissolved in methanol and concentrated in vacuo four times to give the title compound a colourless oil (3.37 g)
