The benzylidene compounds 8a and 8b, obtained by condensation of the 2,3-cycloalkenopyridines 7a and 7b with 3-methoxybenzaldehyde, are converted by catalytic hydrogenation to their benzyl derivatives 9a and 9b.Reduction of the corresponding methoiodides 10a and 10b with sodium borohydride leads to the title compounds 11a and 11b.
