実験手順

A solution of bromobenzene (15.7 g) in ether (50 ml) was added dropwise with cooling to magnesium turning (2.4 g) under an atmosphere of nitrogen. A solution of 1-(4-chlorophenyl)-cyclobutanecarbonitrile (19.1 g) prepared in a similar manner to that described in Example 1 for the 1-(3,4-dichlorophenyl)cyclobutane carbonitrile in ether (50 ml) was added and the ether replaced by dry toluene (130 ml). The reaction mixture was heated on a steam bath for one hour. A sample (20 ml) of the resulting solution was added to a solution of sodium borohydride (1 g) in diethyleneglycoldimethyl ether (60 ml) and the mixture was stirred for one and a half hours. Water (60 ml) was added slowly and the aqueous layer extracted with toluene. The toluene extracts were washed with water, dried and evaporated to give a residue which was dissolved in methanol (50 ml). 6N Hydrochloric acid (5 ml) was added and the soltution filtered and evaporated. Trituration with dry acetone gave α-[1 -(4-chlorophenyl)cyclobutyl]benzylamine hydrochloride (m.p. 277°-279° C.) (Formula I R1 =Ph; R2 =H; R3, R4 =H; R5 =4--Cl; R6 =H).
