Selective reduction of a mixture of methyl 4-chloromethyl-2-thiophenecarboxylate (I) and the 5-chloromethyl isomer II, prepared by chloromethylation of methyl 2-thiophenecarboxylate (III), gave pure 4-chloromethyl derivative I and 5-methyl-2-thiophenecarboxylate (V) which on treatment with sulfuryl chloride was converted into the 5-chloromethyl isomer II.

Recently with the increase in advanced age population, the osteoporosis becomes the object of public attention in the field of orthopedics. The surface topography of the bone by scanning electron microscopy (SEM) is one of the most useful means to study the bone metabolism, that is considered to make clear the mechanism of the osteoporosis. Until today many specimen preparation methods for SEM have been reported. They are roughly classified into two; the anorganic preparation and the simple preparation. The former is suitable for observing mineralization, but has the demerit that the real surface of the bone can not be observed and, moreover, the samples prepared by this method are extremely fragile especially in the case of osteoporosis. On the other hand, the latter has the merit that the real information of the bone surface can be obtained, though it is difficult to recognize the functional situation of the bone.
