Reaction Steps

A solution of the product of Stage 82.d (16.2 g; 55.7 mmol) in THF (70 ml) is treated with a solution of 4-methylpiperidine (23 ml; 195 mmol). The mixture obtained is agitated at ambient temperature for 2 hours. Water (200 ml) and dichloroethane (200 ml) are added. The organic phase is washed with an aqueous solution of sodium chloride (concentrated to 20% by weight; 100 ml), dried over magnesium sulphate and concentrated under reduced pressure. By crystallization of the residue from diethylether, the product in the title is obtained (18.3 g; 93% yield) in the form of a white crystalline solid (M.p. 170–171,5° C.).
