Product 1

HCID 587642112-[4-(2-{2-Cyclopentyl-5-[(2-ethyl-5-oxo-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-7-yl)methyl]-4-hydroxy-6-oxo-3,6-dihydro-2H-pyran-2-yl}ethyl)-2-fluorophenyl]-2-methylpropanenitrile

Procedure

The title compound was prepared on a 0.5-mmol scale analogously to example B(19): except using 2-{4-[2-(2-cyclopentyl-4,6-dioxo-tetrahydro-pyran-2-yl)-ethyl]-2-fluoro-phenyl}-2-methyl-propionitrile from step 3 of example A(84) in place of 6-[2-(3-chloro-4-isopropoxy-phenyl)-ethyl]-6-cyclopentyl-dihydro-pyran-2,4-dione and 2-ethyl-5-oxo-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidine-7-carbaldehyde from step 2 below in place of 1-ethyl-3,5-dimethyl-1H-pyrazole-4-carbaldehyde. Yield: 10 mg (4%). 1H NMR (300 MHz, DMSO-d6): δ 1.29 (t, 3H), 1.35-1.7 (s, m overlap, 14H), 1.99 (m, 2H), 2.38 (m, 1H), 2.63 (m, overlap, 3H), 2.75 (d, 1H), 3.03 (q, 2H), 3.48 (ABq, 2H), 6.06 (s, 1H), 7.10 (m, overlap, 2H), 7.35 (m, 1H), 10.98 (s, 1H). LC-MS (APCI) calcd for C30H33FN2O4S: 564.22, found (M+H+): 565.2 m/z.
