Reaction Steps
A cooled (0° C.) solution of tetrahydro-pyran-3-carboxylic acid (2.831 g, 21.752 mmol) in dichloromethane (60 mL) and N,N-dimethylformamide (5 drops) was treated with oxalyl chloride (2.0 mL, 23.927 mmol). After stirring at room temperature for 2 h, benzyl alcohol (2.5 mL, 23.927 mmol) was added. After stirring at room temperature for 2 h and standing overnight, the volatiles were removed in vacuo and the residue was purified by silica gel chromatography using a 50 g Isolute cartridge eluted with a continuous gradient of iso-hexanes/ethyl acetate 1:0 to 4:1 to afford the title compound (4.587 g, 96%) as a white solid. 1H NMR (300 MHz, CDCl3) δ 1.58-1.88 (m, 3H), 2.03-2.13 (m, 1H), 2.62-2.72 (m, 1H), 3.47 (ddd, J=11.4, 9.6, 3.4 Hz, 1H), 3.63 (dd, J=11.4, 9.1 Hz, 1H), 3.85 (app dt, J=11.1, 3.8 Hz, 1H), 4.06 (ddd, J=11.4, 4.0, 1.6 Hz, 1H), 5.12, 5.17 (ABq, JAB=12.5 Hz, 2H), 7.31-7.46 (m, 5H).
