실험 절차

Formula 202 where R2 is H; R3 is Cl; R5 is Benzyl; R6 is Isopropyl; R6′ is H; Ra and Rb are Methyl; W and Z are —N═; X and Y are —C═: To a solution of (±)-{2-[1-(3-benzyl-7-chloro-4-oxo-3,4-dihydro-pteridin-2-yl)-2-methyl-propylamino]-1,1-dimethyl-ethyl}-carbamic acid tert-butyl ester (1.63 g, 3.16 mmol) in dichloromethane (40 mL) is added trifluoroacetic acid (10 mL). The resultant solution is maintained at ambient temperature overnight and concentrated under reduced pressure. The residue is dissolved in dichloromethane (50 mL) and washed with saturated aqueous sodium bicarbonate (40 mL). The aqueous layer is extracted with dichloromethane (50 mL) and the combined extracts are dried over magnesium sulfate, filtered and concentrated under reduced pressure to give (±)-2-[1-(2-amino-2-methyl-propylamino)-2-methyl-propyl]-3-benzyl-7-chloro-3H-pteridin-4-one which is used in the subsequent step without purification.
