Procedure
To a mixture of 2.89 g (10.62 mmol) of 3-amino-piperidine-1,4-dicarboxylic acid 1-tert-butyl ester 4-ethyl ester [WO 01/70673, Example 134] and 4-(2-methyl-quinolin-4-ylmethoxy)-benzenesulfonyl chloride hydrochloride (4.0 g, 11.8 mmol) in CH2Cl2 (40 mL) at 0° C. was added saturated aqueous NaHCO3 (40 mL). The solution was allowed to warm to 25° C. over 19 h. The reaction was then diluted with CH2Cl2 (100 mL) and water (30 mL), the organic layer was washed with water (2×50 mL), dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by Biotage Flash 40M chromatography, eluting with 1:2 ethyl acetate-hexanes, to afford 3-[4-(2-methyl-quinolin-4-ylmethoxy)-benzenesulfonylamino]-piperidine-1,4-dicarboxylic acid 1-tert-butyl ester 4-ethyl ester as a white solid (1.6 g, 25.8%). MS: 584 (M+H)+.
