Reaction Steps

A 4 N solution of hydrogen chloride in dioxane (0.68 ml, 2.71 mmol) was added to a solution of the compound of step 6 (0.185 g, 0.27 mmol) in 2.7 ml of anhydrous DCM and the mixture stirred at room temperature for 2.5 h. After evaporation of the solvents, the obtained solid was triturated with anhydrous diethyl ether/DCM (9:1) and dried in vacuo at 45° C. to give 0.131 g of the title compound in the form of 3-(2-{(S)-4-[2-(3-fluoro-2-methyl-benzyl)-1-phenyl-indolizine-3-carbonyl]-piperazin-2-yl}-acetylamino)-2,2-dimethyl-propionamide hydrochloride as a light green powder with the following characteristics:
