YieldReaction ConditionsOperation in experiment
With hydrogenchloride; tin(ll) chloride; In Saline; ethanol; water; at 95 - 100℃; for 0.166667 - 0.25h;pH 5.0;succinate buffer; To a sealed 5.0 mL vial were added HYNIC-Lys(OMe)-2-TPP (1.0-100 mug), 0.4 mL of in 0.25 M succinate buffer (pH=5.0), 0.2 mL of ethanol, and 0.4 mL of <strong>[5704-04-1]tricin</strong>e solution (25-100 mg/mL in 0.25 M succinate buffer, pH=5.0). The mixture was immediately degassed under vacuum for 1-2 minutes. The vial containing the mixture was placed in a lead pig (to shield radiation). After addition of 0.5 mL of 99mTcO4- solution (20-30 mCi/mL in saline), and 25 muL of SnCl2.2H2O solution (1.0 mg/mL in 0.1 N HCl), the mixture was heated in a water-bath at 95-100 C. for 10-15 minutes. After cooling to room temperature, a sample of the resulting solution was analyzed by radio-HPLC and ITLC. The labeling yield was >90%. In all the cases, formation of [99mTc]colloid was minimal.

The reactor was charged with 55.2 mL of a 67% solution of dimethyloctadecyl[3- (trimethoxysilyl)propyl]ammonium chloride, 40g of tricine, and 300 mL DMF. The mixture was heated to 145 °C (pot temp) and the methanol was collected until the head temp drops and no more MeOH evolved. The reaction was then cooled and 8.05 g (2 mol eq) of sodium methoxide was added with stirring. The DMF was evaporated at reduced pressure to yield a semi-solid. Toluene (250ml) was added, the mixture stirred at room temp for 1 hour, and then evaporated at reduced pressure. Acetonitrile (250ml) was added, the suspension stirred at room temp for 1 hour, and then evaporated at reduced pressure. This process was repeated until DMF no long was evident by NMR. The resultant product was placed under high vac overnight to yield an off-white solid which readily dissolved in water but soon formed a suspension.

Stage #1: sodium 2-bromoacetate; 2-amino-2-hydroxymethyl-1,3-propanediol In methanol; water at 60℃; for 4h; Stage #2: at 65℃; for 6h; Acidic conditions; 5 Example 5 Preparation method of tris (hydroxymethyl) methylglycine, comprising the following preparation steps: Preparation step S1: Under stirring conditions, a mixture of compound I trimethylolomethane, compound A, reaction solvent methanol and water was added to the drying reactor of 1L, the molar ratio of compound I and compound A was 1:2, the reaction oil bath temperature was 60 °C, the reaction pressure was 0MPa (gauge pressure), and the reaction time was 4h. After the completion of the reaction, it is reduced to room temperature, the insoluble substances are filtered out, the filtrate is rotated under reduced pressure and evaporated to remove the solvent, concentrated, and the crude product of Compound II is prepared; Wherein, Compound A is sodium bromoacetate. Preparation step S2: Under stirring conditions, 20g of compound II was added to the 1L drying reactor, and after acid-base treatment, the sodium salt became the corresponding acid, the reaction oil bath temperature was 65 °C, the reaction pressure was 0MPa (gauge pressure), and the reaction time was 6h. After the reaction is completed, it is reduced to room temperature, the insoluble matter is filtered out, the filtrate is evaporated under reduced pressure and rotated to remove the solvent, concentrated, and the crude product of tris (hydroxymethyl) methylglycine is prepared, with a crude product yield of 93%. Preparation step S3: Under dry conditions, using drying closed equipment, the crude tris (hydroxymethyl) methylglycine obtained in step S2 was dissolved in a mixture of purified solvent methanol and water, and then recrystallized, and then crystallized, filtered and dried at low temperatures to obtain a refined tri(hydroxymethyl) methylglycine product with a fine purity of 99.6%.
