Reaction Steps

A mixture of 2-{1-[4-(4-methoxy-benzenesulfonyl)-piperazin-1-yl]-ethyl}-6-oxo-1,6-dihydro-pyrimidine-5-carboxylic acid ethyl ester (90 mg, 0.2 mmol), cyclopentyl iodide (46 μL, 0.4 mmol), and potassium carbonate (138 mg, 1 mmol) in DMF (1 mL) was heated to 90° C. for 1 day. The reaction mixture was then filtered and purified by HPLC (in the absence of TFA) to yield the product. 1H NMR (400 MHz, CDCl3) δ 8.91 (s, 1H), 7.68 (d, J=8.8 Hz, 2H), 6.99 (d, J=8.8 Hz, 2H), 5.58 (m, 1H), 4.36 (q, J=7.1 Hz, 2H), 3.89 (s, 3H), 3.84 (m, 1H), 3.04 (m, 4H), 2.73 (m, 4H), 1.83 (m, 8H), 1.40 (m, 6H); HPLC ret. time 2.80 min, 10-99% CH3CN, 5 min run; ESI-MS m/z 519.5 (M+1)+.
