2(1H)-Pyrimidinone, hydrochloride (1:1) Use and Manufacturing
To a solution of General procedure: Ribose-1, 2-cyclicphosphate (5) was prepared following the published method (15, 32). The reactionof 5 and nucleobases was conducted in an Eppendorf tube containing nucleobase[adenine (8), hypoxanthine (9), 2, 6-diaminopurine (10), or General procedure: Threose-1, 2-cyclicphosphate (7) was prepared following the published method (15). The reactionwas conducted in an Eppendorf tube containing nucleobase [adenine (8), hypoxanthine(9), The procedure for the synthesis of 5-bromo-2-hydroxypyrimidine 3c is a variation of that published by Crosby and Berthold (J. Chem. Soc. 1960, 25, 1916). To a solution of 2-hydroxypyrimidine HCl (100 g, 0.75 mol) in H2O (1.2 L) Br2 was added (135 g, 0.84 mol) slowly with stirring. The reaction mixture was continuously stirred for approximately 30 min. The solution was heated to 80° C. to drive of excess Br2 and HBr. The solvent was concentrated further under vacuum and the residue recrystallized from 90percent aqueous ethanol to afford 5-bromo-2-hydroxypyrimidine 3c (111 g, 84percent).Step 1 The procedure for the synthesis of 5-bromo-2-hydroxypyrimidine used is a variation of that published by Crosby and Berthold, J. Chem. Soc. 25, 1916, (1960). To a solution of Step 1.1 5-Bromo-hydroxypyrimidine Bromine (67.00 g, 0.419 mol) is added slowly dropwise to a stirred solution of The following 2-hydroxypyrimidine derivatives were prepared analogously: STR79 84 g (0.525 mole) of bromine were added to a solution of 66 g (0.5 mole) of EXAMPLE 10 STR43 168 g (1.05 moles) of bromine were added dropwise at room temperature to a solution of 132.5 g (1 mole) of Preparation of 5-Bromo-2-chloro-pyrimidine 2-Pyrimidinol hydrochloride (13.26 g, 100 mmol) is dissolved in 2N NaOH (50 ml) and bromine (17.98 g, 112.5 mmol) is added over 15 min. The mixture is stirred for 45 min at r.t. and then concentrated in vacuo to yield a brownish solid. _A. 5-bromopyrimidin-2-ol To a 500 mL 3 neck flask equipped with magnetic stirrer, addition funnel, and thermometer was charged 6.63 grams (g) of
