Reaction Steps

At 0° C., a solution of 7-Amino-N-methyl-2,3-dihydroisoindole-1-one (232.6 mg, 1.43 mmol) in DMF (2.0 mL) is treated with 60% NaH (89.8 mg), stirred at the same temperature for 1.5 h, treated with a solution of 2,4,5-trichloropyrimidine (0.557 g) in DMF (3.5 mL), stirred for 1 h, and warmed to room temperature. After furthermore stirring for 13 h, the mixture is treated with sat. aqueous NH4Cl (6 mL), and the resulting brown precipitates are collected by a filtration, followed by washing with H2O, hexane, and CH3CN to give 7-(4-Amino-2,5-dichloropyrimidin-4-yl)amino-N-methyl-2,3-dihydroisoindole-1-one (130.2 g, 0.416 mmol) in 26%. Brown solid. Rf (CH2Cl2/EtOAc 1:1) 0.50. 1H-NMR (400 MHz, CDCl3): 3.22 (s), 4.43 (s), 7.15 (d, J=8.0), 7.59 (dd, J=8.0, 8.0), 8.24 (s), 8.71 (d, J=8.0), 11.05 (br. s).
