Intermediate 33: 2-(Tetrahydro-2/-/-pyran-4-yl)ethyl methanesulfonate To 2-(tetrahydro-2H-pyran-4-yl)ethanol (3,3g) in dry dichloromethane (100 ml) at O0C and under nitrogen was added triethylamine (4.6 ml), followed by methanesulphonyl chloride (2.6 ml) dropwise over 5 minutes. The reaction was stirred until the ice in the bath melted and left overnight at room temperature. The reaction was washed with saturated aqueous sodium bicarbonate (40 ml). The organic layer was dried by passing through a hydrophobic frit and concentrated in vacuo to yield the title compound as a yellow oil (5.4g).1 H NMR (DMSO): 4.24 (2H, t), 3.82 (2H, m), 3.80 (3H, s), 3.27 (2H, m), 2.50 (5H, m), 1.60 (2H, m).
