Abstract

PURPOSE: To obtain the titled compound simply in high yield in high purity effective as a remedy for a closing disorder of respiratory tract, etc., having bronchodilatory action, etc., by reacting phenyloxazolidinone with a dihalogenoalkane in the presence of water.
CONSTITUTION: A compound shown by the formula I (R is H, lower alkyl, alalkyl, or acyl as a protecting group) is reacted with a compound shown by the formula X-(CH2)n-X (X is halogen; n is 4W12) in the presence of water in an inert organic solvent (e.g., methanol, etc.), to give a compound shown by the formula II, which is optionally hydrolyzed to remove the protecting group or converted to an acid addition salt. When the reaction is carried out in the presence of a catalytic amount of a base (e.g., Na, Ca, etc.), the OH-protecting group (R) is removed by hydrolysis simultaneously with both the cleavage of oxazolidinone ring and the condensation of the dihalogenoalkane.
