[方法A]
1H NMR (400 MHz, DMSO-d6), δ (ppm, TMS): 10.00 (1H, br s; -NH2 +-), 9.24 (1H, br s; -NH2 +-), 8.31 (1H, d, J = 8.4; ArH), 8.23 (1H, d, J = 8.0 Hz; ArH), 8.16 (1H, br s; ArH), 8.08-7.96 (4H, m; ArH), 7.82 (1H, t, J = 8.0 Hz; ArH), 7.69-7.58 (3H, m; ArH), 5.47-5.36 (1H, m; -CH(CH3)-), 3.70-3.54 (2H, m; -CH2-), 3.41-3.26 (2H, m; -CH2-), 1.72 (3H, m, J = 6.4 Hz; -CH(CH3)-).
塩酸(R)−(1−ナフチル)エチルアミン(1.5g)、パラホルムアルデヒド(0.3g)、3−(トリフルオロメチル)アセトフェノン(1.8g)、30%w/w塩酸水溶液(0.1g)、エタノール(4.5g)及び水(1.5g)を攪拌下で反応器に投入し、十分な変換がHPLCによって確認されるまでマイクロ波照射(最大250W)下で5分間反応させた。次に、水(10.0g)及びトルエン(3.0g)を添加し、得られた懸濁液を25℃で攪拌した。室温での濾過により標記化合物(1.6g)を単離し、水及びメチル2−プロパノールで洗浄し、50℃で乾燥した。

(R)−3−(1−(ナフタレン−1−イル)エチルアミノ)−1−(3−(トリフルオロメチル)フェニル)プロパン−1−オール塩酸塩(IX)(35.0g、85.393mmol)をトルエン(150ml)に20℃で懸濁させ、塩化チオニル(11.2g、94.141mmol)をゆっくりと添加する。反応混合物を30℃〜40℃で4〜5時間攪拌した後、溶媒を真空下で留去する。蒸留/補充サイクルを数回行って、残ったトルエン性スラリーをイソプロパノールで洗い流す。得られるイソプロパノール溶液を1時間還流させた後、45℃まで冷却し、メチルtert−ブチルエーテル(MTBE)(70ml)を添加する。このようにして得られる懸濁液を45℃で1時間攪拌した後、0℃まで冷却し、1時間熟成させる。濾過を行い、3:1vol/volのイソプロパノール/MTBE混合液で洗浄し(2×20ml)、真空下55℃で乾燥して、(R)−3−クロロ−N−(1−(ナフタレン−1−イル)エチル)−3−(3−(トリフルオロメチル)フェニル)プロパン−1−アミン塩酸塩(X)と(R,E)−N−(1−(ナフタレン−1−イル)エチル)−3−(3−(トリフルオロメチル)フェニル)プロパ−2−エン−1−アミン塩酸塩(XI)の95.8:4.2(HPLC面積%)混合物(29.6g)を白色粉末として得る。
(R)−3−(1−(ナフタレン−1−イル)エチルアミノ)−1−(3−(トリフルオロメチル)フェニル)プロパン−1−オール塩酸塩(IX)(50.0g、121.990mmol)をMTBE(200ml)及び水(80ml)に室温で懸濁させる。水酸化ナトリウム(30%w/w水溶液)を滴下(17.1g、128.250mmol)して発熱反応を制御し、出発固形物が完全に溶解するまで混合物を攪拌する。次に、有機層を分離し、中性pHとなるまで水で繰り返し洗浄する。MTBEをトルエンで洗い流し、得られるトルエン性溶液に塩化チオニル(16.7g、140.372mmol)をゆっくりと添加しながら、10℃〜20℃で維持する。反応混合物を60℃まで加熱し、4時間維持するか、又はIPCが正になるまで(HPLCによる)維持する。反応終了時にMTBEを投入し(170ml)、混合物を80℃〜85℃まで加熱し、微量の水を共沸除去する。混合物を60℃まで冷却し、MTBEを再添加した後、10℃まで冷却し、2時間熟成させる。濾過を行い、1:1vol/volのトルエン/MTBE混合液で洗浄し(3×40ml)、真空下55℃で乾燥して、(R)−3−クロロ−N−(1−(ナフタレン−1−イル)エチル)−3−(3−(トリフルオロメチル)フェニル)プロパン−1−アミン塩酸塩(X)と(R,E)−N−(1−(ナフタレン−1−イル)エチル)−3−(3−(トリフルオロメチル)フェニル)プロパ−2−エン−1−アミン塩酸塩(XI)の96.2:3.8(HPLC面積%)混合物(46.1g)を白色粉末として得る。

(R)−3−クロロ−N−(1−(ナフタレン−1−イル)エチル)−3−(3−(トリフルオロメチル)フェニル)プロパン−1−アミン塩酸塩(X)(15.0g、35.021mmol)、メタノール(150ml)、不均一系触媒、及び最後に添加剤をオートクレーブに投入し、不活性雰囲気に曝露した後、20℃で攪拌しながら100kPaの水素ガスで加圧する。一旦反応が終了(HPLCによるIPC)した時点で、セライト(登録商標)(Celite(登録商標))パッドによる濾過を行い、溶媒を除去し、最後に、添加剤を用いない場合には国際特許出願WO2010/094674の実施例13の教示に従って再結晶化を行って最終生成物(シナカルセト塩酸塩)を単離する。重炭酸ナトリウムを塩化水素失活剤(クエンチャー)として反応混合物で用いる場合には、水を添加した後、セライト(登録商標)(Celite(登録商標))パッドによって反応混合物を濾過する。メタノールを真空下で除去した後、酢酸イソプロピル(150ml)を添加し、出発懸濁液が完全に溶解するまで30%w/w水酸化ナトリウムを投入する。次に、有機層を分離し、中性pHになるまで水で洗浄し、pHが2〜3になるまで30%w/w塩酸水溶液で処理し、濃縮してシナカルセト塩酸塩を得るが、必要に応じて、エーテル、エステル溶媒、又はそれと少量のアルコール溶媒との混合物から再結晶化する(結果の詳細については次表参照)。
