Reaction vessel in oil bath set to 100 °C. 2.15pm o/n 20 hours - LCMS shows product (489) and SM (470) 26 hours - ratio of product : SM looks better by MS. 2 x o/n - small SM peak remaining in MS. Concentrated onto silica and purified on ISCO. 40g column, 4:1 H:EA, then gradient up to ~1:1 EA:MeOH. Can't find product by LCMS in any fractions. NMR of polar fractions may be acid from Buchwald coupling. Need to purify SM on column, repeat.
