methyl 2-(benzylideneamino)-2-phenylacetate

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 8 (40.3 g, 0.2 mol) in dichloromethane (600 mL) was added triethyl amine (24.24 g, 0.24 mol) dropwise. After stirring for 30 min, benzaldehyde (21.2 g, 0.2 mol) was added dropwise, followed by the addition of MgSO4 (240 g, 2 mol). The mixture was stirred overnight. After filtration, the filtrate was evaporated to give compound 9 (49 g, 96.8%). 1H NMR (400 MHz, CDCl3) δ 3.72 (s, 3 H), 5.22 (s, 1 H), 7.30-7.39 (m, 6 H), 7.53-7.56 (m, 2 H), 7.82-7.85 (m, 2 H), 8.34 (s, 1 H). The mixture was stirred overnight After filtration the filtrate was evaporated
