The present invention relates to a process for the preparation of 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman, the enantiomers and its salts, characterised in that 5-(4-fluorophenyl)pyridine-3-carbaldehyde is reacted directly with aminomethylchroman or its salts under reducing conditions to give 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman, and the latter is, if desired, converted into one of its physiologically acceptable salts by treatment with an acid.
Provided are an iminopyridine derivative having a selective α1D adrenergic receptor antagonistic action and useful as an agent for the prophylaxis or treatment of a lower urinary tract disease and the like, and a screening method for a compound having an α1D adrenergic receptor antagonistic action. An α1D adrenergic receptor antagonist containing a compound represented by the formula:
wherein each symbol is as defined in the specification, or a salt thereof, and a method of screening for an agent having an α1D adrenergic receptor antagonistic action for the prophylaxis or treatment of a lower urinary tract disease, which includes measuring the bladder smooth muscle tension of rats with bladder outlet obstruction.
