To a solution of N-methyl-3-(2-(3-methyl-1H-1,2,4-triazol-1-yl)-5-nitrophenoxy)propan-1-amine (Preparation L, 1.20 g, 4.15 mmol) in acetonitrile (50 mL) was added diisopropylethylamine (0.731 g, 5.66 mmol) followed by 2,4-dichloro-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (Preparation R, 1 g, 3.77 mmol) at room temperature. The reaction mixture was stirred at room temperature for 18 h. The solvent was removed under reduced pressure and the residue was taken up in dichloromethane (10 mL) and silica (2 g). The resultant slurry of the compound on silica was subjected to flash chromatography using a Teledyne Isco instrument (12 g RediSep silica column, 50% ethyl acetate in pet-ether) to get 2-chloro-N-methyl-N-(3-(2-(3-methyl-1H-1,2,4-triazol-1-yl)-5-nitrophenoxy)propyl)-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (1.2 g, 61.2%) as a light yellow solid. LC-MS (M+H)+=518.2. 1H NMR (400 MHz, CDCl3) δ ppm 8.95 (1H, s), 8.05-7.93 (3H, m), 7.30-7.11 (5H, m), 4.35-4.31 (2H, m), 4.18-4.14 (1H, m), 3.87-3.70 (2H, s), 3.28 (3H, s), 3.21-3.07 (2H, m), 2.54-2.50 (1H, m), 2.27-2.24 (2H, m), 2.01-1.98 (1H, m).
