Reaction Steps

To a RT solution of tert-butyl 4-(prop-2-yn-1-yloxy)piperidine-1-carboxylate (0.826 g, 3.45 mmol) in 1,4-dioxane (10 mL) was added 4.0M HCl solution in 1,4-dioxane (1.80 mL, 7.20 mmol). After 2 h an additional amount of 4.0M HCl solution in 1,4-dioxane (1.80 mL, 7.20 mmol) was added and the reaction was stirred for 1 h. The solvent was removed in vacuo to yield the titled compound as a white crystalline solid (632 mg, quant).
