1-氯-2-异氰酸根合-2-甲基丙烷

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Benzothiazol-6-ylamine (1.8 g, 12.00 mmol) was added portion wise to solution of 1-chloro-2-isocyanato-2-methyl-propane (2 g, 13.60 mmol) in toluene (20 mL) over a period of 5 minutes. The resulting mixture was stirred at room temperature for 2½ days. The reaction was monitored by TLC (5% MeOH in CHCl3). The reaction mixture was concentrated and extracted with ethylacetate. The organic layer was dried over Na2SO4 and concentrated. Purification by column chromatography on silica gel (1% MeOH in CHCl3) afforded 630 mg of the product (16.57% yield). The reaction mixture was concentrated extracted with ethylacetate The organic layer was dried over Na2SO4 concentrated Purification by column chromatography on silica gel (1% MeOH in CHCl3)

实验步骤: 4-Methyl-pyridin-3-ylamine (1.98 g, 18.33 mmol) was added to solution of 1-chloro-2-isocyanato-2-methyl-propane (I-200c: 3 g, 20.40 mmol) in toluene (30 mL). The resulting mixture was stirred at room temperature for 3 days. The reaction was monitored by TLC (5% MeOH in CHCl3). The reaction mixture was filtered and the residue was dried to afford 4.3 g of the product (87.75% yield). The reaction mixture was filtered the residue was dried
