실험 절차
4-Amino-6-chloro-N-(3-fluoro-5-methoxyphenyl)pyrimidine-5-carboxamide (458 mg, 1.54 mmol) was treated with boron tribromide (1M in dichloromethane, 0.46 ml, 4.6 mmol) an using dichloromethane (7 ml) as a solvent according to the method described in Example 23. The solid residue (394 mg, 71% yield) was used in the next synthetic step without further purification. Purity 91%.
