Reaction Steps

TFA (182 μL, 2.36 mmol) was added to a solution of (R)-tert-butyl 2-(N-(4-chlorobenzyl)-4-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)benzamido)ethylcarbamate (49 mg, 0.094 mmol) in DCM (1 mL). The mixture was stirred at room temperature for 1.5 hours. The mixture was concentrated in vacuo. The crude product was purified by reverse phase HPLC to give (R)-N-(2-aminoethyl)-N-(4-chlorobenzyl)-4-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)benzamide as an oil (9 mg, 22%). MS (APCI+) [M+H]+421.2. 1H NMR (D2O, 500 MHz) δ 9.09 (s, 1H), 7.81 (d, J=8.5 Hz, 2H), 7.63 (d, J=8.0 Hz, 2H), 7.35 (d, J=8.5 Hz, 2H), 7.15 (D, J=8.0 Hz, 2H), 4.63 (s, 2H), 3.87 (t, J=6.5 Hz, 2H), 3.82-3.79 (m, 1H), 3.26-3.11 (m, 4H), 2.63 (s, 2H), 2.50-2.42 (m, 1H), 1.86-1.81 (m, 1H), 0.86 (s, J=7.00 Hz, 3H).
