Participants

Reaction Steps

68.2 g. (0.3 mole) 2,3-dihydro-2,2-dimethyl-7-(2'-chloro-ethoxy)-benzofuran (prepared according to Examples 1 or 2) and 49.86 g. (0.3 mole) triethylphosphite are stirred at 140°-146° C. for 60 hours and heated. When the reaction is completed the obtained yellowish brown oily product is purified by vacuum distillation by distilling off the volatile contaminations at 0.5 torr. The cuts are collected until 148° C. and the distillation residue is a pure product according to gas chromatographic analysis. The product is a pale yellow oily liquid, nD24.5 =1.5101 (compound No. 1).
