A mixture of 29 g (0.072 mol) of the N-ethyl-bis-phthalimide (9), 80 ml of 95% hydrazine, and 300 ml of ethanol was refluxed for 2 hours. The reaction mixture was then cooled to room temperature and allowed to stand overnight. Evaporation under reduced pressure gave a pale yellow solid that was dried for 8 hours at 110° C. and reduced pressure of 0.1 mm Hg. The solid, amounting to 31.5 g, was stirred for 90 minutes in 150 ml of 10% hydrochloric acid and filtered. When the filtrate was neutralized with potassium hydroxide, a heavy precipitate occured which was filtered, dried, and recrystallized from aqueous dimethyl formamide to give 6.5 g of the amino-phthalazinedione (11) as a white powder, m.p. 255°-257° C.

YieldReaction ConditionsOperation in experiment
With hydrogenchloride; 1,1'-carbonyldiimidazole In tetrahydrofuran; sodium hydroxide; ethanol 6-{N-Ethyl-N-[4-(thyroxinylamido)butyl]amino}-2,3-dihydrophthalazine-1,4-dione (13). 6-{N-Ethyl-N-[4-(thyroxinylamido)butyl]amino}-2,3-dihydrophthalazine-1,4-dione (13). A mixture of 4.36 g (5 mmol) of N-trifluoroacetylthyroxine (2), 0.8 g (5 mmol) of carbonyldiimidazole, and 50 ml of tetrahydrofuran was refluxed for 10 minutes. The solvent was removed under vacuum to leave a solid residue of the imidazolide (3). This intermediate was not characterized but was immediately combined with a suspension of 1.38 g (5 mmol) of the amino derivative (11). After stirring for 2 days at room temperature, the solvent was removed under high vacuum and the solid residue washed with 80 ml of 10% hydrochloric acid. The trifluoroacetyl blocking group was removed by dissolving 2.07 g of the crude product in 35 ml of 0.5 M sodium hydroxide. After one hour at room temperature, the solution was neutralized to pH 5.0 with concentrated hydrochloric acid. A precipitate formed that was washed with H2 O and dried. The dried solid was chromatographed on a column of 200 g of silica gel 60 (E. Merck, Darmstadt, West Germany) eluding with a 7:3 volume to volume (v:v) mixture of ethanol and 1 M triethylammonium bicarbonate, collecting 10 ml fractions. Fractions numbered 49 to 65 were combined and evaporated to give 680 mg of a cream-colored solid. This solid was taken up in 50 ml of 50% dimethylformamide and reprecipitated by the addition of H2 O.

EDC (260 mg, 1.5 eq) was added and the resulting mixture was stirred overnight at room temperature, protected from light. After this time LCMS analysis (Analytical C18 Column 2.1 x 50 mm, PDA @ 322 nm, m/z = 373 Es+) revealed product formation > 65%. The ABEI-glutarate reaction mixture was added rapidly by dropper pipette to a 500 mL Erlenmeyer flask containing 300 mL of vigorously stirring ethyl acetate and mixed for 20. The mixture was then transferred to a 500 mL separatory funnel and washed with 75 mL of saturated sodium chloride solution. The organic layer was further washed with deionized water (25 mL x 2) and dried with Na2S04. The solvent was evaporated using a rotary evaporator with a water bath temperature of 55°C to 65°C. Compound la was purified by crystallization from MeOH and the collected solids were dried under a stream of nitrogen in a heating block set at 50°C and lyophilized overnight. Compound la, obtained in 45 % yield, was identical by HPLC, PDA and mass spectral characterization to the compound obtained by procedure A.
