Abstract: A thin-type collapsible foot stand includes a base unit, a first rotatable unit and a second rotatable unit. The base unit includes a base body having a first pivot portion, a first connection portion and a first extending portion. The first rotatable unit includes a rotatable platform having a second pivot portion corresponding to the first extending portion, a second connection portion corresponding to the first connection portion, and a second extending portion corresponding to the first pivot portion. The second rotatable unit includes two rotatable support frames. Each rotatable support frame includes a support body disposed between the base body and the rotatable platform, a first pivot structure connected between one end portion of the support body and the first pivot portion, and a second pivot structure connected between the other end portion of the support body and the second pivot portion.

Abstract: A method of synthesizing 6,7-substituted 4-anilino quinazoline employs 3,4-substituted benzoic acid as an initial reactant, and the 6,7-substituted 4-anilino quinazoline is obtained by an esterifying step, a nitrating step, a reducing step, a cyclizing step, and an one-pot reaction. In the above method, the initial reactant has low cost and yield. of the 6,7-substituted 4-anilino quinazoline is high, therefore, production cost can be reduced effectively, and competitive power of the product of the 6,7-substituted 4-anilino quinazoline can be improved.
