실험 절차

To a solution of 2,4-dichloro-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (160 mg, 0.60 mmol) in NMP (2 mL) was added cyclobutanamine (129 mg, 1.81 mmol) dropwise. The mixture was stirred at RT for 3 hrs. 8 mL of water was added to precipitate out the product. The solid was filtered out and air-dried to give a crude 2-chloro-N-cyclobutyl-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (177 mg, 0.57 mmol, 94% yield), which was used for the next step without any purification. LC-MS (M+H)+=300.1
