Procedure:
To a mixture of 2-methoxy-5-(methoxymethoxy)benzene (30 g, 0.178 mol, 1 eq.) and diisopropylamine (507 uL, 3.6 mmol, 0.02 eq.) in THF (500 mL) was added methyl lithium (1.6 M/THF, 200 mL, 0.32 mol, 1.8 eq.) at −40° C. Upon the completion of addition, the mixture was warmed to 0° C., continued to stir at 0° C. for 3 h, cooled back down to −40° C. and added DMF (24.7 mL, 0.32 mol, 1.8 eq.) slowly. The mixture was then stirred at −40° C. for 1 h, quenched with a mixture of HCl (12 N, 120 mL) and THF (280 mL), warmed to rt, and added water (200 mL). The pH of the mixture was adjusted to pH 8-9 with solid K2CO3. The aqueous layer was extracted with EtOAc (300 mL) twice. The combined organic layers were dried over Na2SO4 and concentrated to give 2-methoxy-5-(methoxymethoxy)benzaldehyde (33.5 g, 95.7%) as a brown solid, which was used for next step without further purification. 1H NMR (400 MHz; CD3OD) 7.90 (s, 1H), 6.92 (s, 1H), 5.64 (s, 1H), 5.20 (s, 2H), 3.84 (s, 3H), 3.48 (s, 3H).

Procedure:
Well-dried magnesium (8.3 g) and THF (20 ml) were put in a reaction vessel under a nitrogen atmosphere, and heated to 50° C. 3-Fluorobromobenzene (8) (60.0 g) dissolved in THF (300 ml) was slowly added dropwise thereto in the temperature range of 40° C. to 60° C., and the mixture was stirred for another 60 minutes. Then, 4-heptylcyclohexanone (9) (50.0 g) dissolved in THF (150 ml) was slowly added dropwise thereto in the temperature range of 50° C. to 60° C., and the mixture was stirred for another 60 minutes. The reaction mixture obtained was cooled to 30° C., and then poured into a vessel containing an aqueous 1N—HCl solution (900 ml) and ethyl acetate (500 ml), and mixed. The mixture was then allowed to stand until it had separated into two phases of organic and aqueous phases, and an extractive operation was carried out. The organic phase obtained was fractionated, washed with water, a saturated aqueous solution of sodium hydrogencarbonate and water, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, giving 80.0 g of 4-heptyl-1-(3-fluorophenyl)-cyclohexanol (10). The compound (10) obtained was a yellow oil.

Procedure:
The ketone prepared as described above (5.4 g) was mixed with N-methylformamide (18 ml), 98% formic acid (4 ml) and 25% aqueous methylamine (0.6 ml) and the mixture heated under reflux for sixteen hours. The mixture was poured into water and extracted with dichloromethane. The extract was washed, dried and evaporated to give a residue which was heated under reflux with concentrated hydrochloric acid (10 ml) for six hours. The mixture was evaporated to dryness and the residue dried by repeated addition and vacuum evaporation of an industrial methylated spirit/toluene mixture. The solid residue was recrystallised from propan-2-ol to give N-methyl-2-[1-(4-chlorophenyl)-cyclobutyl]-1-methylethylamine hydrochloride (m.p. 193°-194° C.) (Formula I R1, R2 =H; R3 =Me; R4 =H; R5 =4-Cl; R6 =H; R7 =Me; R8 =H).
