반응 단계
A 7.9 g. (0.1 mol) sample of pyridine was added dropwise to a solution of 16.4 g. (0.1 mol) 2,3-dihydro-2,2-dimethyl-7-benzofuranol and 9.9 g. (0.1 mol) phosgene in 100 ml. benzene at about 25° C. The reaction mixture was stirred at 25° C for 2 hours, filtered and evaporated under reduced pressure. The solid residue was washed with hexane and dried to give the product, m.p. 85°-87.5° C. Elemental analysis for C11H11O3Cl showed:
