A series of carbinols 3a-f was prepared starting from methanols 1a-f via oxidation with pyridinium chlorochromate to aldehydes 2a-f, followed by a Grignard reaction of the latter. Reaction of 3a-f with ω-chloroalkyldialkylamine hydrochlorides afforded a series of aminoether derivatives 4g-t. Compounds 4i,m-p,s showed a good analgesic activity in the acetic acid writhing test in mice. Moreover, compounds 4h,l,s exhibited a moderate anti-inflammatory activity in the carrageenan-induced edema assay in rats.
