Procedure

iso-Propylmagnesium chloride solution (2M in tetrahydrofuran, 72.9 mL) was added to a stirred solution of 2-chloro-5-iodo-N-[(4-methoxyphenyl)methyl]-N-(tricyclo [3.3.1.13,7]dec-1-ylmethyl)benzamide (Example 15a) (72.87 g) in anhydrous tetrahydrofuran (1 L) at 0° C. under nitrogen. After 30 minutes, copper(I) bromide dimethylsulphide complex (0.68 g) followed by (R)-(−)epichlorohydrin (11.4 mL) were added. The mixture was warmed to 30° C. for 2 hours then diluted with saturated sodium bicarbonate solution (1 L) and water (500 mL) then extracted with ethyl acetate (2×1 L). Organic extracts were dried over anhydrous magnesium sulphate, filtered and evaporated under reduced pressure. The residual oil was dissolved in methanol (600 mL), stirred overnight and the precipitated solid filtered and dried in vacuo to give the titled compound (52.25 g).
