실험 절차

To a solution of 2-methyl-N-{(1R)-1-[6-(trifluoromethyl)-3-pyridinyl]ethyl}-2-propanesulfinamide (41.6 g, 141 mmol) in methyl alcohol (470 mL) at 0° C. was added hydrogen chloride (4.0 M in dioxane; 106 mL, 424 mmol). After 30 min, the mixture was concentrated to dryness. The residue was recrystallized using ethyl alcohol (15 mL) and ether (40 mL). The white solid was filtered and dried under reduced pressure to give the hydrochloride salt of the title compound (26.3 g). MS 191.2 (M+1). 1H NMR (500 MHz, CD3OD): δ 8.83 (d, J=2.2 Hz, 1H); 8.17 (d, J=8.2 Hz, 1H); 7.93 (d, J=8.2 Hz, 1H); 4.69 (q, J=6.9 Hz, 1H); 1.70 (d, J=6.9 Hz, 3H).
