実験手順
A mixture of 0.7 parts of isocyanatomethane, 2.5 parts of N-[1-(2-aminoethyl)-4-piperidinyl]-1-[(5-methyl-2-furanyl)methyl]-1H-benzimidazol-2-amine and 135 parts of tetrahydrofuran was stirred for 3 hours at room temperature. The precipitated product was filtered off and dried, yielding 1.2 parts (41.1%) of N-methyl-N'-[2-[4-[[1-[(5-methyl-2-furanyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]urea; mp. 200.1° C. (compound 40).
