Reaction Steps

318 mg of rac-N-[5-(o-methoxybenzyl)-6-[2-[(tetrahydro-2H-pyran-2-yl]oxy]ethoxy]-4-pyrimidinyl]-p-vinylbenzenesulfonamide, 5.3 mg of osmium tetroxide and 270 mg of sodium(meta)periodate were added in succession to a mixture of 1.5 ml of water and 4 ml of dioxane at room temperature. After stirring at room temperature for 1 hour, the dioxane was distilled under reduced pressure. Thereafter, the aqueous phase was extracted three times with ethyl acetate. The ethyl acetate was washed twice with water and once with NaCl solution (saturated), dried and distilled under reduced pressure. The residue was chromatographed over 30 g of SiO2 with CH2Cl2 /ethyl acetate and yielded 150 mg of rac-p-[[5-(o-methoxybenzyl)-6-[2-[(tetra-hydro-2H-pyran-2-yl)oxy]ethoxy]-4-pyrimidinyl]sulfamoyl]-benzaldehyde as white foam. MS: 527 (M); 443 ##STR12## (--OCH3 +SO2).
