Chloroformates are key reagents for synthesizing carbonates and carbamates. The present study reports a novel photo-on-demand in situ synthesis of chloroformates with a CHCl3 solution containing a primary alkyl alcohol. It further allowed the one-pot synthesis of carbonates and carbamates through subsequent addition of alcohols or amines, respectively.

Synthetic impurities that are present in dabigatran etexilate mesylate were studied, and possible pathways by which these impurities are formed during the manufacturing process were examined. The impurities were monitored by high-performance liquid chromatography, and their structures were determined by mass spectrometry and 1H and 13C NMR. Potential causes for the formation of these impurities are discussed, and strategies to minimize their formation are also described.
CARBONIC ACID ESTER AND MAGNETIC RECORDING MEDIUM
-
, (2008/12/07)
A carbonic acid ester is provided that is represented by the formula below and has a melting point of no greater than 0° C. (In the formula, R1 and R2 independently denote a saturated hydrocarbon group, R1 is a branched chain, and R2 is a straight or branched chain). There is also provided a magnetic recording medium that includes a non-magnetic support and, above the support, at least one magnetic layer including a ferromagnetic powder dispersed in a binder, the magnetic layer including the carbonic acid ester. Furthermore, there is provided a magnetic recording medium including a support and, above the support, a non-magnetic layer including a non-magnetic powder dispersed in a binder, and above the non-magnetic layer, at least one magnetic layer including a ferromagnetic powder dispersed in a binder, the non-magnetic layer and/or the magnetic layer including the carbonic acid ester.
