Procedure

The resulting 1-acetamido-4-methoxymethoxy-2-nitro-benzene is treated with sodium hydroxide in methanol, warmed briefly on a steam bath for about 15 minutes until the reaction is complete, diluted with water and extracted with dichloromethane to afford 1-amino-4methoxymethoxy-2-nitrobenzene. This latter compound is treated in accordance with the first paragraph of Example VI to afford 1-(3-methoxycarbonyl-2-thioureido)-4-methoxymethoxy-2-nitrobenzene. This latter compound is reduced in accordance with the iron reduction technique as set forth in the third paragraph of Example XIX to afford 2-amino-1-(3-methoxycarbonyl-2-thioureido)-4-methoxymethoxybenzene. This latter compound is treated in accordance with the first paragraph of Example XVI to afford 2-acetamido-1-(3-methoxycarbonyl-2-thioureido)-4-methoxymethoxybenzene.
