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 4,6-dimethyl-2-mercaptonicotinonitrile 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 1.53-1.71 (m, 8H) 2.01 (s, 3H) 2.06 (m, 2H) 2.34 (m, 1H) 2.37 (s, 3H) 2.58 (m, 2H) 2.83 (d, J=17.9 Hz, 1H) 2.93 (d, J=15.0 Hz, 1H) 3.80 (s, attenuation due to proximity to H2O peak) 6.98 (s, 1H) 7.02 (d, J=8.2 Hz, 1H) 7.11 (d, J=5.0 Hz, 1H) 7.23 (d, J=1.9 Hz, 1H). MS (APCI) calcd for C27H29ClN2O4S: 513.06; found M=513.1.
