Reaction Steps

A suspension of tert-butyl 4-(1-hydroxypropan-2-yl)piperazine-1-carboxylate (0.782 g, 3.2 mmol) in a mixture of ethyl acetate (10 ml) and methanol (10.00 mL), was treated drop-wise with 4.0M HCl in dioxane (12.00 ml, 48.00 mmol) at room temperature. The reaction mixture was stirred for 18 h. The reaction mixture was diluted with ether and the white solid filtered off, washed with ether and air dried to give 2-(piperazin-1-yl)propan-1-ol (0.525 g, 76%), as its dihydrochloride salt.
