반응 단계
A 100 mL round bottom flask equipped with magnetic stir bar was charged with 1 g aminodiphenylmethane, 2 mL triethylamine in 20 mL CH2Cl2. The reaction was cooled to 0° C. and 1 g of methyl 3-chlorosulfonyl-2(R)-methylpropionate was slowly added. The reaction was stirred 1 hour then concentrated in vacuo. The residue was partioned between ethyl acetate and water. The organic phase was washed with brine, dried, and concentrated in vacuo. Trituration from Et2O/hexanes gave 1.15 g of methyl 3-[N-(diphenylmethyl) aminosulfonyl]-2(R)-methylpropionate as a white solid. HRMS (M+Li): calcd. 354.1351, obs 354.1569.
