Procedure
tert-Butyl (2-{[7-(2,4-dichlorophenyl)imidazo[1,2-c]pyrimidin-5-yl]amino}propyl)carbamate (Example 36A) (700 mg, 1.6 mmol) is dissolved in dichloromethane (20 ml), and trifluoroacetic acid (2.5 ml, 32 mmol) is added. The resulting solution is stirred at RT for 1 h, concentrated in a rotary evaporator and dried on the vacuum line. 1 g of the product is obtained.
