PROCEDURE
实验过程
A mixture of (R)-3-(2-chlorobenzamido)-N-methyl-N-(piperidin-4-yl)-2,3-dihydro-1H-indene-5-carboxamide (see stage 2 illustrative compound H-214) (230 mg, 0.559 mmol, 1 eq), 5-chloro-3-methyl-1,2,4-thiadiazole (83 mg, 0.615 mmol, 1.1 eq) and Cs2CO3 (363 mg, 1.118 mmol, 2 eq) in dioxane (10 ml) was heated for 2 h at 80° C. When the reaction was complete according to TLC monitoring, the reaction mixture was concentrated under reduced pressure. The residue was taken up in dichloromethane (50 ml), washed with water (30 ml) and saturated sodium chloride solution (30 ml) and dried over sodium sulfate. The solvent was removed by distillation under reduced pressure and the crude product was purified by column chromatography (Alox, 0.5% methanol/dichloromethane). The desired product was in the form of a white solid. Yield: 59% (170 mg, 0.333 mmol)
