Procedure

Formula 203 where R2 is H; R3 is Cl; R5 is Benzyl; R6 is Isopropyl; R6′ is H; Ra and Rb are Methyl; Rc is 3-Fluoro-4-methyl-phenyl-; W and Z are —N═; X and Y are —C═: To a solution of (±)-2-[1-(2-amino-2-methyl-propylamino)-2-methyl-propyl]-3-benzyl-7-chloro-3H-pteridin-4-one (133 mg, 0.32 mmol) in dichloromethane (3 mL) is added triethylamine (90 μL, 0.64 mmol), followed by 3-fluoro-4-methylbenzoyl chloride (51 μL, 0.35 mmol). The resultant solution is stirred at ambient temperature for 3 hours, quenched with saturated aqueous sodium bicarbonate (5 mL) and diluted with dichloromethane (5 mL). The aqueous layer is extracted with dichloromethane (5 mL) and the combined extracts are dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue is purified by silica gel chromatography (10-20% ethyl acetate/hexanes) to give (±)-N{2-[1-(3-benzyl-7-chloro-4-oxo-3,4-dihydro-pteridin-2-yl)-2-methyl-propylamino]-1,1-dimethyl-ethyl}-3-fluoro-4-methyl-benzamide.
