实验步骤: To 5-(3-chlorophenylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde (20 mg, 0.074 mmol) in 0.5 mL EtOH was added 1-methylimidazolidine-2,4-dione (8.4 mg, 0.074 mmol) and piperidine (7.5 μL, 0.074 mmol). The mixture was heated at 70° C. overnight. The solid formed was isolated by filtration and air dried to give 5-((5-(3-chlorophenylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)-1-methylimidazolidine-2,4-dione. LCMS (M+1=369) The solid formed was isolated by filtration and air dried

实验步骤: Prepared according to the procedure described in Example 92 using 3,5-diisopropyl-4-hydroxybenzaldehyde (2.7 g, 13 mmoles) and 1-methyl hydantoin (1.4 g, 12 mmoles). Recrystallization from acetonitrile gave the pure product (0.4 g), mp 197°-208° C. Prepared Recrystallization from acetonitrile
