Reaktionsschritte

The product of Example 304F (0.284 g, 0.61 mmol) and cyclopentanone (0.80 mL, 9.04 mmol) in N,N-dimethylacetamide (2 mL) were reacted at 130° C. for 40 minutes in a microwave reactor in a sealed tube. The reaction was concentrated under a stream of nitrogen warmed through a manifold heated to 165° C. The resulting residue was triturated with diethyl ether and filtered to give the title compound (0.210 g, 65%). 1H NMR (300 MHz, DMSO-d6) δ ppm 1.72 (m, 2 H) 1.87 (m, 2 H) 2.16 (m, 2 H) 2.71 (m, 2 H) 5.18 (s, 2 H) 7.31 (m, 11 H) 8.10 (d, J=8.46 Hz, 1 H) 16.22 (s, 1 H).
