91% In dichloromethane; at 20℃; for 15h; Example 3; N-(2-dH-l,2,3-triazol-4-yl')propan-2-ylV4-r3.,4-dichlorophenoxy')piτ)eridine- 1 -sulfonamide[0094] Step A: Preparation of tert-butyl 2-methylbut-3-yn-2-ylcarbamate: A solution of dimethylpropargylamine (3.0 g, 36 mmol) and Boc anhydride (7.5 g, 34 mmol) in DCM (73 rnL) was stirred at room temperature for 15 hours. The reaction mixture was washed with dilute aqueous HCl, and the organic layer was dried with MgSO4 and concentrated in vacuo to afford tert-butyl 2-methylbut-3-yn-2-ylcarbamate (6.0 g, 91%) as a solid. 1H NMR (400 MHz.

The reaction mixture was washed with dilute aqueous HCl5 and the organic layer was dried with MgSO4. The organic layer was concentrated in vacuo to afford tert-butyl 2-methylbut-3-yn-2-ylcarbamate (6.0 g, 91%) as a white solid. 1H NMR (400 MHz. CDCl3) δ 2.30 (s, IH), 1.55 (s, 3H), 1.53 (s, 3H), 1.46 (s, 9H).
82% at 50℃; for 0.5h; A mixture of 1 ,1 -dimethylpropargylamine (4.2g) and B0C2O (1 1 g) without solvent was warmed up to 50C for 30 min. The resulting solid was treated with n-hexane (10 mL) and the product was collected by filtration to give white solid (7.6 g, yield 82%)
35.6% at 50℃; for 0.5h; A mixture of 2-methyl-3-butyn-2-amine (1 mL) and di-tert-butyl dicarbonate (2.07 g) without solvent was warmed up to 50 CC for 30 mm. The resulting solution was diluted with nhexane (5 mL) and the crystals formed were, subsequently, collected by filtration, washed with hexane and dried under vacuum to give 620 mg of the title compound (yield: 35.6%).
