YieldReaction ConditionsOperation in experiment
3.5 g (42%) With pyridine; diphosphorus pentasulfide; In ethanol; water; acetic acid; Chlorine was led into a solution of 9.9 g of 1-ethyl-uracil in 150 ml of glacial acetic acid until iodine-potassium-starch paper reacted positively and 1-ethyl-uracil was no longer detectable by thin-layer chromatography (ca. 0.5 hours). The mixture was evaporated in vacuo at 40 and the crystalline residue recrystallized from 300 ml of ethanol; yield 10.0 g (81%) of colorless, fine needles of 1-ethyl-5-chlorouracil; melting point 244-247. 1.74 Grams of 1-ethyl-5-chlorouracil were mixed with 4.44 g of phosphorus pentasulfide and 0.1 ml of water and the mixture treated with 30 ml of pyridine and boiled at reflux for 3.75 hours. The mixture was then evaporated in vacuo at 40, the residue suspended in 30 ml of water and treated with 30 ml of 2-N hydrochloric acid. the crystals obtained were filtered off under suction, washed with water and recrystallized from 1-ethyl-5-chloro-1,2-dihydro-4-mercapto-2-oxo-pyrimidine; melting point 217-220. In a manner analogous to that described in Example 1 6.27 g of cephalothin sodium salt were reacted 3.04 g of 1-ethyl-5-chloro-1,2-dihydro-4-mercapto-2-oxo-pyrimidine prepared above to give (7R)-3-[[(1-ethyl-5-chloro-1,2-dihydro-2-oxo-4-pyrimidinyl)-thio]methyl]-7-[2-(2-thienyl)-acetamido]-3-cephem-4-carboxylic acid as the sodium salt; yield 3.5 g (42%); melting point from 185 (decomposition); [α]D20 = -95.2 (c = 0.394 in water).

YieldReaction ConditionsOperation in experiment
83% In water; butan-1-ol; at 20℃; for 48.0h; General procedure: The synthesis and physical characterization of four beta-lactam-based chlorhexidine GUMBOS, namely chlorhexidine di-ampicillin, chlorhexidine carbenicillin, chlorhexidine di-cephalothin and chlorhexidinedi-oxacillin, were performed using methods previously reported by Cole et al. (2013) [24], but with slight modification. Briefly, stoichiometric amounts of <strong>[56-95-1]chlorhexidine diacetate</strong> and beta-lactam antibiotic, with the latter in slight excess, was stirred for 48 h at room temperature in a butanol:water (1:1) mixture to ensure the complete formation of the beta-lactam-based chlorhexidine GUMBOS. After removing butanol from the GUMBOS products, they were purified by washing several times with cold deionized water and dried overnight with a high vacuum. The structures of chlorhexidine di-ampicillin, chlorhexidine carbenicillin, chlorhexidine di-oxacillin and chlorhexidine di-cephalothin (Figure 1) were mainly confirmed by NMR, mass spectrometry and elemental analysis, among other spectroscopic data.
