Reaction Steps
At 0° C., TMSCHN2 (2.0 M in ether, 15 mL) was added dropwise to a mixture of 2-(1-(tert-butoxycarbonyl)piperidin-4-yl)acetic acid (6272 mg, 25.78 mmoL) in Toluene (60 mL) and MeOH (60 mL). After stirring at room temperature for 1 h, the mixture was concentrated. The crude tert-butyl 4-(2-methoxy-2-oxoethyl)piperidine-1-carboxylate was used as it is without further purification.
