  • Processes for producing 4-bromo-2-methoxybenzaldehyde
    Patent number: 8692026
    Abstract: A new synthesis of 4-bromo-2-methoxybenzaldehyde is reported from 1,4 dibromo 2-fluorobenzene. First, 2-fluoro-4-bromobenzaldehyde is prepared through metal halogen exchange and formylation with a formyl source at 0° C. After crystallization, this intermediate is reacted with methanol in the presence of potassium carbonate. Subsequently, 4-bromo-2-methoxy-benzaldehyde is crystallized.
    Type: Grant
    Filed: July 1, 2011
    Date of Patent: April 8, 2014

  • Processes for producing 3-(methylthio) thiophene
    Patent number: 8487120
    Abstract: Processes are provided for producing 3-(methylthio)thiophene by (i) combining at least an alkyl lithium, one or more alkanes and an ether to form a first combination, (ii) at a temperature of about ?30° C. to about ?25° C. and over a time period of at least about 30 minutes, adding 3-bromothiophene diluted in an ether to the first combination to form a second combination, (iii) at a temperature of about ?25° C. to about ?20° C. combining at least the second combination and dimethyl disulfide, and (iv) yielding at least the 3-(methylthio)thiophene.
