実験手順

To a stirring solution of (2S,3S,5R)-2-(3,5-difluorophenyl)-2-hydroxy-3,5-dimethylmorpholine-4-carboxylic acid chloromethyl ester (1410) (2.24 g, 6.67 mmol) in 150 mL of anhydrous tetrahydrofuran was added the furosemide cesium salt (10c) (3.09 gm, 6.67 mmol) and sodium iodide (1.10 gm, 7.34 mmol). The mixture was heated to ˜60° C. and monitored by TLC (1:1 heptane:ethyl acetate). After heating for 6 hours, TLC analysis indicated a slowing down of product formation with starting materials remaining. The reaction was halted so as not to allow by-product formation. The solvent was removed from the crude yellow mixture, and it was dried onto silica gel. This crude material was purified on an Optix Companion Automated Chromatography system using an 80 gm silica cartridge and eluting with ethyl acetate/heptane (0 to 70% over 50 minutes). This material was dried on a vacuum pump for 24 hours and afforded 0.560 g of (2S,3S,5R)-4-[5-(aminosulfonyl)-4-chloro-2-[(2-furanylmethyl)amino]benzoyloxymethoxycarbonyl]-2-(3,5-difluorophenyl)-3,5-dimethyl-2-morpholinol (1420) as a light yellow foamy solid. Melting point range was 105° C. to 110° C. Elemental analysis calculated for [C26H26N3 0.3 EtOAc]: C, 49.76; H, 4.36; N, 6.4. found C, 50.08; H, 4.65; N, 6.23. 1H NMR (400 MHz, CDCl3) δ 0.86-0.89 (t, 3H), 1.34 (m, 3H), 3.60-3.67 (m, 1H), 4.23 (m, 1H), 4.33 (m, 1H), 4.45-4.46 (d, 2H), 4.47 (s, 1H), 5.07-5.11 (d, 2H), 6.00-6.05 (dd, 2H), 6.28 (s, 1H), 6.35 (s, 1H), 6.75-6.79 (t, 1H), 6.89 (m, 1H), 7.12-7.14 (br. d, 2H), 7.37-7.39 (d, 1H), 8.53 (br. d., 1H), 8.63 (s, 1H).
