The compound of the formula (11) is prepared using tri alkyl tin azide. Ortho tolyl benzonitrile (OTBN of the formula (8) is reacted with trialkyl tin azide followed by hydrolysis to give tetrazole derivative of the formula (9). The tetrazole derivative is reacted with trityl chloride to give trityl tetrazole derivative of the formula (10), which on radical bromination gives compound of the formula (11). The reaction sequence is given in the Scheme 6.
