実験手順
To a suspension of ethyl 2-(trityloxy)acetate (8.2 g, 23.67 mmol) in EtOH (350 ml), NaOH 6M (7.89 ml, 47.3 mmol) was added at RT. The suspension slowly turned into a solution. After 1 hour, EtOH was removed under vacuum and the remaining crude was partitioned between HCl 2N and DCM. The organic phase was separated, dried over Na2SO4 and evaporated under vacuum. 2-(Trityloxy)acetic acid was obtained (7.42 g, 23.31 mmol, 98% yield) and used as such in the following reaction without further purification.
