887590-25-2, 11.2: trans-4-(5-Hydroxyadamantan-2-ylcarbamoyl)-3,4-dihydro-2H-quinoxaline-1-carboxylic acid tert-butyl ester 0.4 g of 3,4-dihydro-2H-quinoxaline-1-carboxylic acid tert-butyl ester is placed in 8 ml of dichloromethane at 0 C. under nitrogen. 0.69 ml of triethylamine and 0.202 g of triphosgene are added. The mixture is stirred at ambient temperature for 3 h, then 1 ml of dimethylformamide and 0.285 g of trans 4-aminoadamantan-1-ol are added and stirring is maintained for 18 h. The reaction medium is washed with a saturated aqueous sodium hydrogencarbonate solution. The organic phase is dried over magnesium sulphate and concentrated to dryness. The crude product obtained is chromatographed on silica gel, elution being carried out with a gradient of a dichloromethane/methanol (99/1 to 95/5) mixture. 0.54 g of trans-4-(5-hydroxyadamantan-2-ylcarbamoyl)-3,4-dihydro-2H-quinoxaline-1-carboxylic acid tert-butyl ester is obtained. M+H+=428
As the paragraph descriping shows that 887590-25-2 is playing an increasingly important role.
