실험 절차

To a solution of 2-(I-benzylpiperidin-4-yloxy)-6-(1-(propylsulfonyl)-1,2,3,6-tetrahydropyridin-4-yl)benzo[d]thiazole (1.812 g, 3.54 mmol) in dichloroethane (30 mL) at 0° C. was added 1-chloroethyl carbonochloridate (0.497 mL, 4.60 mmol). Upon completion of addition, the reaction mixture was stirred at 0° C. for 15 min and then heated to reflux, where it stirred for 1 h. At the conclusion of this period, the volatiles were removed under vacuum and the resulting sample was dissolved in MeOH (30 mL) and then heated to reflux, where it stirred for 1 h. After this time, the reaction mixture was cooled to rt and then concentrated under reduced pressure to yield a residue. The residue was diluted with CH2Cl2 and washed with aq K2CO3 (saturated, 10 mL) and brine (10 mL). The organic layer was dried (Na2SO4), filtered, and then concentrated to afford Compound 15A (1.405 g, 3.33 mmol, 94% yield). LC/MS (m/z)=422 (M+H)+.
