Reaction Steps

A mixture of hexahydro-1-(phenylmethyl)-4H-azepin-4-one (0.2 mol) and 4-toluene-sulfonylmethyl isocyanide (0.25 mol) in DMF (200 ml) was stirred at 0° C. A solution of potassium tert-butoxide (0.4 mol) in a mixture of 2-methyl-2-propanol (200 ml) and 1,2-dimethoxyethane (200 ml) was added dropwise at 0° C. The mixture was allowed to reach room temperature and stirring was continued for 1 hour. The mixture was stirred in water and this mixture was extracted with DCM. The separated organic layer was dried, filtered and the solvent was evaporated, yielding 48 g of (±)-hexahydro-1-(phenylmethyl)-1H-azepine-4-carbonitrile (intermediate 1).
