Procedure
5-(5-Amino-6-chloropyrimidin-4-yl)amino-1-methyl-1,2-dihydro-2-pyridinone (1 g) and NMP (10 mL) were introduced into a flask and stirred at 40° C. 3-Fluorobenzoyl chloride (0.53 mL, 1.1 eq.) was added dropwise to this suspension, and after additional NMP (3.2 mL) was added thereto and stirred for about 1.5 hours, the reaction solution was elevated to 110° C. and stirred for 3 hours. Ethyl acetate (33 mL) and 10% aqueous sodiumbicarbonate solution (16.5 mL) were added to the reaction solution, and the organic layer was washed with brine (16.5 mL) and concentrated. The concentrate was dissolved by adding DME (16.5 mL) and stirring it at 55° C., and then crystallized by adding water (33 mL). The crystals were collected by filtration and dried at 50° C. for 4 hours, to give 0.94 g of 5-[6-chloro-8-(3-fluorophenyl)-9H-9-purinyl]-1-methyl-1,2-dihydro-2-pyridinone (two-steps, yield 66.7%) (6) 5-[6-Amino-8-(3-fluorophenyl)-9H-9-purinyl]-1-methyl-1,2-dihydro-2-pyridinone
