Hexachloroethane → HCID 86687163, compound

Participants

Reaction Steps

Hexachloroethane (4.34 g, 18.4 mmol) was added portionwise over 5 min at RT to a stirred mixture of Intermediate 101a (2.30 g, 9.2 mmol), triethylamine (3.71 g, 36.8 mmol) and triphenylphosphine (4.82 g, 18.4 mmol) in THF (90 mL). The reaction mixture was stirred at RT for 1 h, then diluted with MeOH and purified by FCC using SCX-2 cartridge. The cartridge was washed with MeOH and the product was eluted with 2M NH3 in MeOH. The compound containing fractions were combined and concentrated in vacuo. The resultant residue was subjected to the follow purification procedure; FCC on silica (0-6% [2M NH3 in MeOH] in DCM), then SCX-2 cartridge (conditions described above) and finally further FCC on silica (0-2% MeOH in EtOAc), to afford the title compound (1.34 g, 62%). 1H NMR (400 MHz, CDCl3): 3.87 (4H, d, J=6.2 Hz), 5.16-5.35 (4H, m), 5.85-6.02 (2H, m), 7.11 (1H, ddd, J=10.0, 7.6, 2.3 Hz), 7.58-7.67 (1H, m), 7.75-7.80 (1H, m).
