Uniform nanopowders of barium aluminate (BaAl2O4) can be synthesized by a facile solution reaction at room temperature using barium and aluminum salts and 2-aminoethanol as a precipitating agent. The asprepared sample showed a good reactivity in the synthesis of benzo[b]thiophene, thieno[2,3-c]thiopyran and thieno[2,3-c]pyridine derivatives. Comparatively the method is efficient and eco-friendly, and finally, a range of compounds with variable functionalities in excellent yield can be achieved.

Paragraph 0129, (2013/03/26)
The purpose is to provide a compound which has an intestinal phosphate transporter (NPT-IIb) inhibitory action and is useful as an active ingredient of an agent for treating and/or preventing hyperphosphatemia. A tetrahydrobenzothiophene compound of the following formula (I) has NPT-IIb inhibitory action and can be used as an agent for treating and/or preventing hyperphosphatemia: wherein, R1 represents -O-lower alkyl, -lower alkylene-phenyl, or the like; R2 and R3 are the same as or different from each other and represent H, lower alkyl, cycloalkyl, aryl, heteroaryl or the like, or, R2 and R3 may be combined with a nitrogen atom to which they bind to form 5- to 7-membered saturated cyclic amino; R4,s are the same as or different from each other and represent halogen, lower alkyl; and n represents 0 to 2.
