    摘要: A laboratory scale low temperature apparatus (1) for carrying out laboratory scale low temperature chemical reactions comprises an insulated pressure container (2) for a coolant, in this case liquid nitrogen at less than minus 1960C, and a reaction vessel (3) in the form of a silvered, vacuum jacketed borosilicate glass vessel in which low temperature reactions are carried out. An outlet (5) from the coolant container (2) is connected to an in-line heater 8 in which the coolant is heated. The in-line heater (8) is connected to a contact heat exchanger (12) in the form of a spiral coil extending into the reaction vessel (3). The temperature in the vessel (3) is monitored by a sensor (25) which provides a signal to a controller which is also connected to the in-line heater (8) to maintain the target temperature in the vessel (3).

    摘要: Atorvastatin lactone is prepared by hydrogenating tert-butyl isopropylidene nitrile to tert-butyl isopropylidene amine and condensing the amine with the diketone of atorvastatin to form acetonide ester. The diol protecting acetonide ester is deprotected to form a diol ester by dissolving the acetonide ester in methanol and treating with an acid. The diol ester is saponified to form a sodium salt. Methanol is removed from the reaction mixture by distillation. The sodium salt is reacidified to the free diol acid and atorvastatin lactone is formed from the diol acid. The atorvastatin lactone is directly dried without further purification.
