Procedure

To a solution of Intermediate 45a (6.0 g, 24.6 mmol) in THF (123 mL) was added lithium aluminium hydride (2.33 g, 61.5 mmol) portionwise, then the mixture was stirred at reflux for 4 h. A further portion of lithium aluminium hydride (1.28 g, 33.6 mmol) was added to the cooled solution, then the mixture was stirred at reflux for a further 8 h. Water (3.75 mL) was added dropwise, followed by 4N aqueous NaOH (11.3 mL) and water (3.75 ml). The mixture was filtered, washed with diethyl ether, dried (MgSO4) and concentrated in vacuo to give the title compound as a yellow oil (3.67 g, 99%). 1H NMR (400 MHz, CDCl3): 2.40-2.52 (9H, m), 2.67 (2H, t, J 2.7), 3.70 (4H, t, J 4.5).
