Operation in experiment
Compounds 41-70 were part of a parallel set prepared in library plate format according to General Procedure L, outlined below. ; L. General Procedure for Plate Preparation-Amide Formation XXI: Resin bound deprotected biarylphenol XVII (prepared from intermediate XII, boronates XIVd and XIVe, following general procedures D-F) was distributed into a 96 well plate, 10 mg of resin (0.013 mmol) per well. To the resin 400 mul of dichloromethane was added, followed by 100 mul of DIEA, followed by 0.13 mmol (10 equiv) of heterocyclic carboxylic acid XXa-XXn was added followed by 61 mg (0.13 mmol, 10 equiv) of PyBrop. The plate was shaken at room temperature for 24 hours, then drained and washed with dichloromethane, methanol/dichloromethane, dimethylformamide, methanol/dichloromethane and dichloromethane. The compounds were cleaved with TFA/dichloromethane (600 mul, 1:1) into a 96 deep well plate and submitted for testing without further purification. (Mass spec results obtained are shown in Table 4). Carboxylic Acids Het-COOH XX:
With hydrogenchloride; 1,1'-carbonyldiimidazole; In tetrahydrofuran; methanol;
Example 141 Synthesis of Compound 141 In 100 mL of methanol, was dissolved 5.90 g (50.0 mmol) of monomethyl malonate, and the resulting solution was mixed with 2.86 g (25 mmol) of magnesium ethoxide followed by stirring at room temperature for 4 hours. The reaction solution was concentrated and the residue was dried under reduced pressure. In 100 mL of tetrahydrofuran, was dissolved 2.80 g (25 mmol) of 2-furancarboxylic acid and the resulting solution was mixed with 4.45 g (27.4 mmol) of carbonyldiimidazole, followed by stirring for 1 hour. The reaction solution was added to a dry magnesium salt and stirred at room temperature for 19 hours. The reaction solution was concentrated; the residue was mixed with 100 mL of 1.5 N hydrochloric acid, extracted with ethyl acetate, and washed with an aqueous sodium hydrogencarbonate solution and saturated sodium chloride water. The resultant was dried over sodium sulfate anhydride, filtered, and concentrated. The residue was distilled (0.06 mmHg, 69 to 75) to give 2.93 g (17.4 mmol, 69.6%) of methyl 2-furancarbonylacetate as an anhydrous liquid.
