Reaction Steps

The compound of step 7 (0.065 g, 0.11 mmol) was dissolved in 1.1 ml of DCM and cooled to 0° C. and a 4 N solution of hydrogen chloride in dioxane (0.54 ml, 2.20 mmol) was added. The mixture was stirred at room temperature overnight and then evaporated to dryness under reduced pressure. The obtained solid was triturated several times with diethyl ether and dried in vacuo at 40° C. 0.053 g of the title compound were obtained in the form of 2-(3-fluoro-2-methyl-benzyl)-1-phenyl-3-(piperazine-1-carbonyl)-indolizine-7-carboxylic acid methylamide hydrochloride as a light yellow solid with the following characteristics:
