반응 단계
Using 117.1 g (1 mol) of N-formylsarcosine, 98.1 g (1 mol) of ethyl propiolate and 638 ml of acetic anhydride, a reaction and post treatment were conducted in a similar manner as in Referential Example 1. The resulting brown oil was distilled under reduced pressure and a 103-104° C. fraction was collected under 4 mmHg, whereby 109.19 g of the title compound were obtained (yield: 71.3%).
