Reaction Conditions

Reaction Steps

2.8 g of 2,3-dihydro-2-methyl-5-benzofuranylmethyl chloride and 3.0 g of 1-(3-hydroxyphenyl)-3-methoxy-3-methylurea were dissolved into 20 ml of dried N,N-dimethylformamide, and 2.5 g of anhydrous potassium carbonate was added thereto. After the mixture was stirred at 80° C. for 4 hours, the reaction mixture was poured into water and extracted with ethyl acetate. After the organic layer was washed with water, it was dried over anhydrous magnesium sulfate and ethyl acetate was dried off. The residue was subjected to silica gel column chromatography using ethyl acetate/n-hexane (1/2) as a developer to obtain 3.7 g of Compound No. 46 shown in Table 2.
