78% With sodium hydroxide; N-(5-Hydroxy-2-pyridinemethylene) hydroxylamine. To 200 mL of 2.5percent (w/w) sodium hydroxide solution was dissolved 5.5 g of 5-hydroxy-2-formylpyridine (45 mmol). Subsequently 12.5 g of hydroxylamine HCl (180 mmol) was added to the solution in one portion. The solution turned cloudy after being stirred for 10 minutes. After stirring at room temperature for 3 h, the precipitate was filtered under vacuum and dried in the air for several days to yield 4.8 g of N-(5-hydroxy-2-pyridinemethylene) hydroxylamine (78percent).

With NaH; In water; N,N-dimethyl-formamide; EXAMPLE 18 Preparation of 2-[(benzyloxycarbonyl)amino]-4-(5-hydroxy-2-pyridyl)-3-R,S-methylbutanoic acid. STR94 A. Methoxyethoxymethyl chloride (MEM) (19 g, 153 mmol) was added to a solution of <strong>[31191-08-9]5-hydroxy-2-pyridinecarboxaldehyde</strong> (18.4 g, 149 mmol)in 300 ml DMF. NaH (6.3 g of 60percent oil dispersion, 158 mmol) were added in portions while cooling the mixture to maintain 20°-30° C. The mixture was stirred an additional 1 hour at 25° C. 5 ml water were added, most of the solvent was evaporated, and water was added to the residue. The mixture was extracted with EtOAc. The extracts were dried over Na2 SO4, filtered, and evaporated to a residue. The residue was chromatographed on silica gel eluding with EtOAc-hexanes (35:65) to obtain 5-[(2-methoxyethoxy)methoxy]-2-pyridinecarboxaldehyde: C10 H13 NO4 (211.22); 1 H-NMR (CDCl3) delta 10.01 (s,1), 8.52 (d,1), 7.93 (d,1), 7.49 (m,1), 5.39 (s,2), 3.80 (m,2), 3.53 (m,2), 3.32 (s,3).

YieldReaction ConditionsOperation in experiment
3.6 g (35%) With ammonium chloride; In tetrahydrofuran; hexane; ethyl acetate; N,N-dimethyl-formamide; EXAMPLE 6 2-[2-(1-Hydroxyhexyl)-5-pyridyloxy]quinoline To a suspension of sodium hydride (3.6 g, 0.15 mol) in dry DMF (150 ml) containing 2-chloroquinoline (24.5 g, 0.15 mol) was added dropwise a solution of <strong>[31191-08-9]5-hydroxypyridine-2-carboxaldehyde</strong> (18.5 g, 0.15 mol) in dry DMF (75 ml). The solution was stirred vigorously with a mechanical stirrer. After the addition was complete (90 min.), the reaction was heated to about 90° C. for 12 hours. Most of the DMF was removed, and the residue was carefully poured into cold water. The aqueous solution was extracted with ethyl acetate (4*30 ml), and the organic extract was washed with water, brine, and then dried over MgSO4. All volatiles were removed to leave the crude aldehyde intermediate (26 g) which was pure enough to be used in the next step. To a cold (-30° C.) solution of 5-(2-quinolinyloxy)-2-pyridine carboxaldehyde (8 g, 0.032 mol) in dry THF (125 ml) was added a solution of pentylmagnesium bromide (prepared from 4.83 g (0.032 mol) of 1-bromopentane and 0.78 g (0.032 mol) of Mg turnings in THF (60 ml). After the addition of the Grignard reagent was complete (-45° C.), the solution was stirred at this temperature for 90 minutes, and allowed to slowly warm up to room temperature in about 2 hours. The reaction was quenched by adding a saturated solution of ammonium chloride. The clear organic layer was decanted, and most of the volatiles were removed. The residue was taken up in ethyl acetate, and then washed with water, brine, and dried over MgSO4. After removal of the ethyl acetate the crude residue (7.7 g) was purified by HPLC (silica gel; 25percent ethyl acetate in hexane) to give 3.6 g (35percent) of pure product.
