Reaction Conditions

Reaction Steps

Amine 3 (90.0 g, ˜0.41 mol) was dissolved in methylene chloride (810 ml). Triethylamine (66.6 g, 0.66 mol) was added and the solution was cooled to 5° C. Methyl chloroformate (47.0 g, 0.50 mol) in methylene chloride (100 ml) was then added slowly and the reaction temperature was maintained between 10° C. and 14° C. After addition was complete, the reaction solution was stirred at room temperature for 12 hours. Water (540 ml) was added. Aqueous phase was separated. Organic phase was concentrated to dryness to afford crude compound 4. The crude product was used in the next step without further purification. 1H NMR (300 MHz, CDCl3) δ 0.279 (s, 9H), 2.86 (d, br, 3H), 3.774 (s, 3H), 4.484 (s, br, 2H), 7.190 (s, br, 2H), 7.46 (d, 2H, J=8.10 Hz).
