    摘要: The present invention provides an efficient stereoselective method for manufacturing (2S,4S)-2-[[(R)-hydroxy-(3R)-cyclic amine-3-yl]methyl]pyrrolidine-4-thiol or a salt thereof which is useful as an intermediate for the manufacture of carbapenem and also provides the intermediate. A method for manufacturing which comprises the step of reacting a compound of the formula (I): (wherein, R1 is a lower alkylsulfonyl group, an optionally substituted arylsulfonyl group or an alkylsilyl group; and R2 is a protecting group for an amino group) with a compound of the formula (II): (wherein, R3 is a substituted or unsubstituted lower alkyl group or aryl group; X is an oxygen atom or a sulfur atom; Y is an azide group or a nitro group; and m is an integer of 2 to 5).

    摘要: Active ingredients such as medicines are mixed with excipient and then kneaded together with binder and solvent such as alcohol or water to prepare a wetted paste. A mold is filled with this paste. Top and bottom surfaces of the paste within the mold are coated with powder such as lubricant in order to avoid possible sticking of the paste to the apparatus during a subsequent compression step. Then a compressive pressure is exerted on the surface of the paste. Thereafter, the tablet is taken from the mold. The molded tablet can contain water-soluble or fat-soluble medicine.
