Cyclohexene → HCID 12082689, compound

Participants

Reaction Steps

A mixture of Compound 14 (1.02 g, 2.05 mmol), 10% Pd/C catalyst (0.52 g), cyclohexene (30 ml) and absolute MeOH (30 ml) were reflux heated for 16 hours under N2. Then the catalyst was filtered off and the filtrate evaporated. The residue (0.66 g of white foam resin) was crystallised out of i-PrOH/Et2O 1:1 (2 ml). Yield: 0.33 g (42%) of beige crystals: Fp>235-239° C.; IR (KBr): 3348 (OH) cm−1; 1H-NMR (CDCl3): 6.62 (d, J=8.0, 1 arom. H); 6.54 (d, J=8.0, 1 arom. H); 4.26 (d, J=7.0, H—C(5)); 3.22 (s, CH3O—C(14)); 2.36 (s, CH3N); Cl-MS: m/z 317 (M++1).
