Yield:186204-35-3 92.6%
Reaction Conditions:
with triethylamine at 0 - 5;Industrial scale;
Steps:
7
Intermediate 1 (10.6 kg, 73.5 mol) is dissolved in a mixture of methylisobutyl ketone (315 1) and triethylamine (35 1). The solution is then cooled tobetween 0°C and 5°C, and mesyl chloride (11.7 1, 151 mol) is added in 60 minutes. After the addition, the mass is stirred until the reaction is complete, and water (315 1) is added. The two phases are then separated, and the organic phase is concentrated to obtain a solution containing 20.44 kg of 2, yield 92.6%.
