Procedure

To a solution of D-(−)-Prolinol (0.205 g, 2.03 mmol) in N,N-Diisopropylamine (0.758 mL, 4.35 mmol) and N,N-Dimethylformamide (4.49 mL, 58.0 mmol) at room temperature was added 8-Bromo-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-2-carbonyl chloride (0.500 g, 1.45 mmol) portionwise. The reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was diluted with ethyl acetate, washed with brine, and concentrated in vacuo to give (8-Bromo-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-((R)-2-hydroxymethyl-pyrrolidin-1-yl)-methanone which was not further purified.
