1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → t-Butyl 3-(4-(cyclopropylamino)thieno[3,2-d]pyrimidine-7-carboxamido)-4-methylphenylcarbamate

Participants

Reaction Steps

4-(Cyclopropylamino)thieno[3,2-d]pyrimidine-7-carboxylic acid (5.3 g, 22.49 mmol) obtained in Step 3 of Preparation Example 4 was dissolved in DMF (60 mL). t-Butyl 3-amino-4-methylphenylcarbamate (6 g, 26.99 mmol) obtained in Step 2 of Preparation Example 9, EDCI (6.5 g, 33.74 mmol), HOBT (6.1 g, 44.98 mmol) and TEA (4.7 mL, 33.74 mmol) were sequentially added to the reaction mixture, which was stirred at room temperature for 24 hours. After the reaction was completed water (120 mL) was added thereto, and the resulting yellow solid was filtered and dried to obtain the title compound without further purification.
