Procedure:
N-[5-(5,6-Dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoyl]-4-cyanoaniline (0.100 g, 0.211 mmol) was dissolved in methanol (6 ml) and after adding thereto an aqueous saturated sodium hydrogencarbonate solution (3 ml), the solution was stirred at room temperature for 3 hours. After the completion of reaction, the reaction solution was diluted with water and then extracted with ethyl acetate. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (hexand:ethyl acetate=1:2) and then recrystallized from ether to obtain the titled compound (0.063 g, 0.146 mmol, 69%).

Procedure:
To a flask fitted with a condenser, stirrer and thermometer were added 20 g. of the dioxalate salt of 2-dimethylaminomethyl-4-(2-aminoethyl)thiomethylthiazole, and 50 ml. of water. The pH of the solution was adjusted to 6.1 by the addition of 52 ml. of 2N aqueous potassium hydroxide, and 7.5 g. of methylcarbonimidodithioic acid, dimethyl ester, was added. The mixture was stirred at 75° for 3 hours, and was then cooled to ambient temperature. Its pH was adjusted to 6.5 by addition of 3.2 ml. of 2N aqueous potassium hydroxide, and 100 ml. of dichloromethane was added with vigorous mixing. The pH was adjusted to 6.5 again with 1 ml. of 2N aqueous potassium hydroxide, and the organic layer was separated and discarded. The aqueous layer was mixed with 100 ml. of additional dichloromethane, and its pH was adjusted to 13 by addition of 55 ml. of 2N aqueous potassium hydroxide. The organic layer was separated, dried over potassium carbonate and evaporated under vacuum to obtain 13.1 g. of product, which was found by NMR analysis to be substantially identical to that of Example 1. Its purity was 94.6% by high performance liquid chromatographic analysis.

The reaction mixture was cooled and poured into water (10 volumes). Aqueous ammonia (S.G. 0.880) was added until the solution was alkaline and the mixture was extracted with ethyl acetate. The extracts were washed with water, dried and on removal of the solvent gave a residue which was purified by preparative layer chromatography on silica gel plates using a 1:1 mixture of dichloromethane and methanol to give 5-ethoxycarbonyl-2-[3-(3-piperidinomethylphenoxy)propyl]benzimidazole as an oil.
