Participants

Reaction Steps

In N,N-dimethylformamide (4 ml) was dissolved the 2-[(4-chlorophenyl)sulfonylmethyl]-1,4-difluorobenzene (101 mg, 0.333 mmol) obtained in Example 5. After addition thereto of t-butyl acrylate (146 μl, 1.00 mmol) and 1,8-diazabicyclo[5,4,0]undece-7-en (151 μl, 1.00 mmol), stirring was conducted at room temperature for 1 week. The reaction mixture was then concentated. The residue thus obtained was subjected to flash chromatoraphy on a silica gel column, and the fraction obtained from the hexane:ethyl acetate=4:1 eluate was concentrated, whereby the title compound (142 mg, 0.329 mmol, 99%) was obtained as a colorless oil.
