Step 2 On reaction with hydrogen chlor ide in an anhydrous solvent, the thiocar bonyl sulfur of the PTC der ivative attacks the car bonyl car bon of the N-terminal amino acid. The N-terminal anino acid is cleaved as a thiazolone derivative from the remainder of the peptide. [Pg.1134]

Reaction of 2 equiv of 2-aminopyridines with 2-hydropolyfluoroalk-2-anoates 351 in MeCN in the presence of NEts at 90 °C for 50 h afforded a mixture of the isomeric 2-oxo-2H- and 4-oxo-4//-pyrido[l,2-n]pyrimidines 110 and 111. Reaction of 3 equiv of 2-amino-pyridines and 2-hydropoly-fluoroalk-2-enoates 351 in MeCN in the presence K2CO3 could be accelerated by ultrasonic irradiation (125W). 2-Amino-6-methylpyridine yielded only 2-substituted 6-methyl-4//-pyrido[l,2-n]pyrimidin-4-ones 111 (R = 6-Me), whereas 2-amino-5-bromopyridine gave a mixture of 7-bromo-4//-pyrido[l,2-n]pyrimidin-4-one (111, R = 7-Br, R = CF2C1) and 2-(chlor-o,difluoromethyl)-6-bromoimidazo[l, 2-n]pyrimidine-3-carboxylate in 44 and 8% yields, respectively (97JCS(P 1)981). Reactions in the presence of K2CO3 in MeCN at 90°C for 60h afforded only imidazo[l,2-n]pyrimidine-3-carboxylates. [Pg.243]

Into a stirred, cooled (10°-15°C) solution of 26.2 grams (0.1 mol) of 2-amino-5-chlorobenzo-phenone (3-oxime in 150 ml of dioxane were introduced in small portions 12.4 grams (0.11 mol) of chloracetyl chloride and an equivalent amount of 3 N sodium hydroxide. The chlor acetyl chloride and sodium hydroxide were introduced alternately at such a rate so as to keep the temperature below 15°C and the mixture neutral or slightly alkaline. The reaction was completed after 30 minutes. The mixture was slightly acidified with hydrochloric acid, diluted with water and extracted with ether. The ether extract was dried and concentrated in vacuo. Upon the addition of ether to the oily residue, the product, 2-chloroacetamido-5-chlorobenzophenone (3-oxime, crystallized in colorless prisms melting at 161°-162°C. [Pg.466]
