乾燥エーテル1000mL中のHEMA24mL(200mmol)に、アルゴン下で4−10℃において、ピリジン16.8mL(213mmol)を加えた。この溶液に、1−クロロエチルクロロカーボネート21.3mL(200mmol)を、30分以上攪拌しながら滴下して加えた。4−10℃での30分の攪拌後、重い沈殿物(化合物B)を濾過により取り除き、濾液を真空下で油状物へ濃縮して、44g(100%)を得た。
、32分で、次の構造式のカーボネートが最終的に出てきた。
乾燥テトラヒドロフラン(THF)250mL中のトリアミノトリメチロールプロパンエトキシレート13.2gに、ピリジン6.32g(80mmol)を加えて、この溶液をよく攪拌しながらアルゴン(Ar)下で4−10℃においてTHF250mL中のクロロアセチルクロリド6.44gに加えた。15分間攪拌した後、反応混合物を室温まで温めて、THFおよび他の揮発性物質を真空下で除去した。得られた固体を、クロロホルム200mL中に溶解させて、次に、当該クロロホルムを飽和重炭酸ナトリウム水溶液100mLで洗浄して、硫酸マグネシウムで乾燥させて、溶媒を真空中で除去した。
無水ジメチルホルムアミド75mL中に溶解させた約15gの上記物質に、セシウムメタクリレート18gを加えて、得られた懸濁液を40−50℃で2時間加熱した。
