反応手順
Methylamine gas was bubbled through a solution of 4-hydroxymethylene-dihydro-2,2,5,5-tetramethyl-3(2H)furanone (5.0 g, 29 mmol) in 50 mL of chloroform for 30 min. The solvents were evaporated. The solid residue was recrystallized from hexanes to give 4.0 g (74%) of dihydro-2,2,5,5-tetramethyl-4-methylaminomethylene-3(2H)furanone as a light yellow solid: mp 80°-82° C.; Anal Calc'd for C10H17NO2 : C, 65.57; H, 9.29; N, 7.65. Found: C, 65.47; H, 9.30; N, 7.60.
