Reaction Steps

To a solution of 1.6M n-butyl lithium in n-hexane (16.5 ml) in toluene (20 ml) at -20° C., under nitrogen, was added a solution of 2-bromo-6,7,8,9-tetrahydro-3-methyl-5H-cyclohepta[b]pyridine (6 g, 0.025 m) in toluene (30 ml) and kept at -20° C. for 0.25 hours. This was blown over into a solution of 3-pyridine carboxaldehyde (2.7 g) in toluene (30 ml) kept at -20° C. The solution was allowed to warm up to room temperature and water added. The organic phase was separated, dried (MgSO4) and evaporated. The solid was recrystallised from ether (twice) to give 1-(6,7,8,9-tetrahydro-3-methyl-5H-cyclohepta[b]pyrid-2-yl)-1-(pyrid-3-yl)methanol (4.32 g, 64%) m.p. 124°-6° C.
