Reaction Steps

The title compound was prepared as described in Example C(70), where 3-chloro-6-[2-(3-chloro-4-methoxyphenyl)ethyl]-6-cyclopentyldihydro-2H-pyran-2,4(3H)-dione was used in place of 3-chloro-6-[2-(5-chloro-2,4-dimethoxyphenyl)ethyl]6-cyclopentyldihydro-2H-pyran-2,4(3H)-dione and 6-methyl[1,2,4]triazolo[1,5-a]pyrimidine-2-thiol was used in place of 6-hydroxy-8-mercaptopurine monohydrate. 1H NMR (500 MHz, DMSO-d6, WET suppression of DMSO-h6 (2.5 ppm) and H2O (3.35 ppm) peak areas) δ 1.52-1.69 (m, 8H) 2.22 (m, 2H) 2.30 (s, 3H) 2.35 (m, 1H) 2.50 (m, 1H, overlap with dmso) 2.62 (m, 1H) 2.73 (d, J=17.6 Hz, 1H) 2.98 (d, J=17.9 Hz, 1H) 3.81 (s, 3H) 7.06 (d, J=8.2 Hz, 1H) 7.24 (dd, J=8.5, 1.9 Hz, 1H) 7.30 (d, J=1.9 Hz, 1H) 8.55 (d, J=1.1 Hz, 1H) 8.67 (d, J=2.2 Hz, 1H).
