実験手順
1M Hydrochloric acid (10 mL) was added to a solution of 2-({3-[(2,4-difluorophenyl)thio]propyl}oxy)tetrahydro-2H-pyran (610 mg, 2.12 mmol) in methanol (10 mL) and stirred at RT for 40 minutes. The methanol was removed in vacuo and the residue adjusted to pH 6 then extracted into ethyl acetate (3×50 mL). The combined organics were washed with brine (50 mL), dried (MgSO4), filtered and reduced in vacuo to give the desired compound as a colourless oil (410 mg). 1H NMR δ (CDCl3): 1.38 (t, 1H), 1.83 (quintet, 2H), 2.97 (t, 2H), 3.77 (q, 2H), 6.81-6.87 (m, 2H), 7.38-7.45 (m, 1H)
